SCES553A - MAY 2004 - REVISED JULY 2004 D Member of the Texas Instruments D D D D D Ioff Supports Partial-Power-Down Mode Widebus+ Family Control Inputs VIH/VIL Levels Are Referenced to VCCA Voltage VCC Isolation Feature - If Either VCC Input Is at GND, Both Ports Are in the High-Impedance State Overvoltage-Tolerant Inputs/Outputs Allow Mixed-Voltage-Mode Data Communications Fully Configurable Dual-Rail Design Allows Each Port to Operate Over the Full 1.2-V to 3.6-V Power-Supply Range D D D Operation I/Os Are 4.6-V Tolerant Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II ESD Protection Exceeds JESD 22 - 4000-V Human-Body Model (A114-A) - 200-V Machine Model (A115-A) - 1000-V Charged-Device Model (C101) description/ordering information This 32-bit noninverting bus transceiver uses two separate configurable power-supply rails. The SN74AVC32T245 is optimized to operate with VCCA/VCCB set at 1.4 V to 3.6 V. It is operational with VCCA/VCCB as low as 1.2 V. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.2 V to 3.6 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, and 3.3-V voltage nodes. The SN74AVC32T245 is designed for asynchronous communication between data buses. The device transmits data from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the outputs so the buses are effectively isolated. The SN74AVC32T245 is designed so that the control pins (1DIR, 2DIR, 3DIR, 4DIR, 1OE, 2OE, 3OE, and 4OE) are supplied by VCCA. This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down. The VCC isolation feature ensures that if either VCC input is at GND, then both ports are in the high-impedance state. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.

MAY 2004 - REVISED JULY 2004 power-up considerations A proper power-up sequence always should be followed to avoid excessive supply current, bus contention, oscillations, or other anomalies. To guard against such power-up problems, take the following precautions: 1. Connect ground before any supply voltage is applied. 2. Power up VCCA. 3. VCCB can be ramped up along with or after VCCA. typical total static power consumption (ICCA + ICCB) Table 1 VCCB 10 VCCA 0V 1.2 V 1.5 V 1.8 V 2.5 V 3.3 V 0V 0 <1 <1 <1 <1 <1 1.2 V <1 <2 <2 <2 <2 2 1.5 V <1 <2 <2 <2 <2 2 1.8 V <1 <2 <2 <2 <2 <2 2.5 V <1 2 <2 <2 <2 <2 3.3 V <1 2 <2 <2 <2 <2 POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 UNIT A SCES553A - MAY 2004 - REVISED JULY 2004 TYPICAL CHARACTERISTICS 6 6 TA = 25C VCCA = 1.2 V TA = 25C VCCA = 1.2 V 5 tPHL - Propagation Delay - ns tPLH - Propagation Delay - ns 5 4 3 2 x + 1 H 0 0 VCCB= 1.2 V VCCB = 1.5 V VCCB = 1.8 V VCCB = 2.5 V VCCB = 3.3 V 10 20 30 40 CL - Load Capacitance - pF 50 4 3 2 x + 1 H 0 60 0 10 20 30 40 50 CL - Load Capacitance - pF Figure 1 6 TA = 25C VCCA = 1.5 V TA = 25C VCCA = 1.5 V 5 tPHL - Propagation Delay - ns tPLH - Propagation Delay - ns 60 Figure 2 6 4 3 2 x + 1 H 0 VCCB = 1.2 V VCCB = 1.5 V VCCB = 1.8 V VCCB = 2.5 V VCCB = 3.3 V 0 10 20 30 VCCB = 1.2 V VCCB = 1.5 V VCCB = 1.8 V VCCB = 2.5 V VCCB = 3.3 V 40 50 5 4 3 2 x + 1 H 0 60 CL - Load Capacitance - pF 0 10 20 30 VCCB = 1.2 V VCCB = 1.5 V VCCB = 1.8 V VCCB = 2.5 V VCCB = 3.3 V 40 50 60 CL - Load Capacitance - pF Figure 3 Figure 4 POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 11 SCES553A - MAY 2004 - REVISED JULY 2004 TYPICAL CHARACTERISTICS 6 6 TA = 25C VCCA = 1.8 V 5 tPHL - Propagation Delay - ns tPLH - Propagation Delay - ns 5 TA = 25C VCCA = 1.8 V 4 3 2 x VCCB = 1.2 V VCCB = 1.5 V VCCB = 1.8 V VCCB = 2.5 V VCCB = 3.3 V + 1 H 0 0 10 20 30 40 50 4 3 2 x + 1 H 0 60 0 10 20 CL - Load Capacitance - pF 6 TA = 25C VCCA = 2.5 V + 5 tPHL - Propagation Delay - ns tPLH - Propagation Delay - ns 5 4 3 2 + H 12 x TA = 25C VCCA = 2.5 V 1 10 20 30 50 60 Figure 6 6 x 40 CL - Load Capacitance - pF Figure 5 0 0 30 VCCB= 1.2 V VCCB = 1.5 V VCCB = 1.8 V VCCB = 2.5 V VCCB = 3.3 V VCCB = 1.2 V VCCB = 1.5 V VCCB = 1.8 V VCCB = 2.5 V VCCB = 3.3 V 40 50 60 H VCCB = 1.2 V VCCB = 1.5 V VCCB = 1.8 V VCCB = 2.5 V VCCB = 3.3 V 4 3 2 1 0 0 10 20 30 40 CL - Load Capacitance - pF CL - Load Capacitance - pF Figure 7 Figure 8 POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 50 60 SCES553A - MAY 2004 - REVISED JULY 2004 TYPICAL CHARACTERISTICS 6 TA = 25C VCCA = 3.3 V TA = 25C VCCA = 3.3 V 4 3 2 x + 1 H 0 0 10 x + 5 5 tPHL - Propagation Delay - ns tPLH - Propagation Delay - ns 6 20 30 VCCB = 1.2 V VCCB = 1.5 V VCCB = 1.8 V VCCB = 2.5 V VCCB = 3.3 V 40 50 H VCCB = 1.2 V VCCB = 1.5 V VCCB = 1.8 V VCCB = 2.5 V VCCB = 3.3 V 4 3 2 1 0 60 0 10 20 30 40 50 60 CL - Load Capacitance - pF CL - Load Capacitance - pF Figure 10 Figure 9 POST OFFICE BOX 655303 * DALLAS, TEXAS 75265 13 SCES553A - MAY 2004 - REVISED JULY 2004 PARAMETER MEASUREMENT INFORMATION 2 x VCCO S1 RL From Output Under Test Open GND CL (see Note A) TEST S1 tpd tPLZ/tPZL tPHZ/tPZH Open 2 x VCCO GND RL tw LOAD CIRCUIT VCCI VCCI/2 Input VCCO 1.2 V 1.5 V 0.1 V 1.8 V 0.15 V 2.5 V 0.2 V 3.3 V 0.3 V CL RL 15 pF 15 pF 15 pF 15 pF 15 pF 2 k 2 k 2 k 2 k 2 k VTP 0.1 V 0.1 V 0.15 V 0.15 V 0.3 V VCCI/2 0V VOLTAGE WAVEFORMS PULSE DURATION VCCA Output Control (low-level enabling) VCCA/2 0V tPLZ tPZL VCCI Input VCCI/2 VCCI/2 0V tPLH Output tPHL VOH VCCO/2 VOL VCCO/2 VCCA/2 VCCO Output Waveform 1 S1 at 2 x VCCO (see Note B) VCCO/2 VOL tPHZ tPZH Output Waveform 2 S1 at GND (see Note B) VOL + VTP VCCO/2 VOH - VTP VOH 0V VOLTAGE WAVEFORMS ENABLE AND DISABLE TIMES VOLTAGE WAVEFORMS PROPAGATION DELAY TIMES NOTES: A.
