ON Semiconductor MC74VHCT374A Octal D-Type Flip-Flop with 3-State Output The MC74VHCT374A is an advanced high speed CMOS octal flip-flop with 3-state output fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. This 8-bit D-type flip-flop is controlled by a clock input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state. The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The VHCT inputs are compatible with TTL levels. This device can be used as a level converter for interfacing 3.3V to 5.0V, because it has full 5V CMOS level output swings. The VHCT374A input and output (when disabled) structures provide protection when voltages between 0V and 5.5V are applied, regardless of the supply voltage. These input and output structures help prevent device destruction caused by supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc. * High Speed: fmax = 140MHz (Typ) at VCC = 5V * Low Power Dissipation: ICC = 4A (Max) at TA = 25C * TTL-Compatible Inputs: VIL = 0.8V; VIH = 2.0V * Power Down Protection Provided on Inputs and Outputs * Balanced Propagation Delays * Designed for 4.5V to 5.5V Operating Range * Low Noise: VOLP = 1.6V (Max) * Pin and Function Compatible with Other Standard Logic Families * Latchup Performance Exceeds 300mA * ESD Performance: HBM > 2000V; Machine Model > 200V * Chip Complexity: 276 FETs or 69 Equivalent Gates DATA INPUTS 2 5 6 9 12 15 16 19 3 D0 4 D1 7 D2 8 D3 13 D4 14 D5 17 D6 18 D7 11 CP OE Q0 Q1 Q2 Q3 Q4 Q5 Q6 Q7 NONINVERTING OUTPUTS 1 DW SUFFIX 20-LEAD SOIC WIDE PACKAGE CASE 751D-05 DT SUFFIX 20-LEAD TSSOP PACKAGE CASE 948E-02 M SUFFIX 20-LEAD SOIC EIAJ PACKAGE CASE 967-01 ORDERING INFORMATION MC74VHCTXXXADW SOIC WIDE MC74VHCTXXXADT TSSOP MC74VHCTXXXAM SOIC EIAJ FUNCTION TABLE INPUTS OE L L L H CP D Q L, H, X H L X X H L No Change Z OE 1 20 VCC Q0 2 19 Q7 D0 3 18 D7 D1 4 17 D6 Q1 5 16 Q6 Q2 6 15 Q5 D2 7 14 D5 D3 8 13 D4 Q3 9 12 Q4 10 11 CP GND Figure 1.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range GND (Vin or Vout) VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V CC ). Unused outputs must be left open. * Absolute maximum continuous ratings are those values beyond which damage to the device may occur. Exposure to these conditions or conditions beyond those indicated may adversely affect device reliability. Functional operation under absolute-maximum-rated conditions is not implied.
