The PI74ALVCH16601 uses D-type latches and D- type flip-flops with 3-state outputs to allow data flow in transparent, latched, and clocked modes. Data flow in each direction is controlled by Output Enable (OEAB and OEBA), Latched Enable (LEAB and LEBA), and Clock (CLKAB and CLKBA) inputs. The clock can be controlled by the Clock Enable (CLKENAB and CLKENBA) inputs. For A-to-B data flow, the device operates in the transparent mode when LEAB is HIGH. When LEAB is LOW, the A data is latched if CLKAB is held at a high or low logic level. If LEAB is low, the A-bus is stored in the latch/flip-flop on the low-to-high transition of CLKAB. When OEAB is low, the outputs are active. When OEABis HIGH, the outputs are in the high-impedance state. Data flow for B to A is similar to that of A to B but uses OEBA, LEBA, CLKBA, and CLKENBA. To ensure the high-impedance state during power up or power down, OE should be tied to Vcc through a pull- up resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver. The PI74ALVCH16601 has Bus Hold which retains the data inputs last state whenever the data input goes to high-impedance preventing floating inputs and eliminating the need for pullup/down resistors. 142 PS8134A 02/23/98(1) PERICOM PEP EE RUPERT ECT ESTATE RATED TA EEO EEA EP EEE ORO ETE E URE T EEE OEEPE ERE EU EU aE eee PI74ALVCH16601 18-Bit Universal Bus Transceiver Product Pin Description Truth Table Pin Name Description Inputs CLKEN Clock Enable Input (Active LOW) _7 Output B CLKENAB | OFAB | LEAB| CLKAB | A OE Output Enable Input (Active LOW) IE Latch Enable (Active HIGH) x H | X x Xx CLK Clock Input (Active HIGH) L H L AX Data I/O Xx L H x H H Bk Datal/O GND Ground H L L x x Bot Voc Power H L L x x Bot L L L tT L L L L t H L L L L x Bot Product Pin Configuration L L L H x Bos OEAB LEAB Al GND A2 A3 Voc A4 A5 AG GND AT AB Ag A10 Al1 Al2 GND A13 A14 A15 Voc A16 AI7 GND A118 OEBA LEBA Ooo oi oo a a pd 1 \\ 56 2 55 3 54 4 53 5 52 6 51 7 50 8 49 9 48 10 47 if 46 12 45 13 44 14 43 15 56-PIN 42 16 A-56 41 17.
