The 74ABT16952 is a dual octal registered transceiver. Two 8-bit registers store data flowing in both directions between two bidirectional buses. Data applied to the inputs is entered and stored on the rising edge of the Clock (n CPXX) provided that the Clock Enable (n CEXX) is Low. The data is then present at the 3-State output buffers, but is only accessible when the Output Enable (n OEXX) is Low. Data flow from A inputs to B outputs is the same as for B inputs to A outputs. Two options are available, 74ABT16952 which does not have the bus-hold feature and 74ABTH16952 which incorporates the bus-hold feature. - Power-up reset - Multiple VCC and GND pins minimize switching noise - Independent registers for A and B buses - Output capability: +64m A/- 32m A - Latch-up protection exceeds 500m A per Jedec Std 17 - ESD protection exceeds 2000V per MIL STD 883 Method 3015 - Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused inputs and 200V per Machine Model QUICK REFERENCE DATA SYMBOL t PLH t PHL CIN CI/O ICCZ ICCL PARAMETER Propagation delay n CPBA to n Ax or n CPAB to n Bx Input capacitance I/O capacitance Quiescent su supply ly current CONDITIONS Tamb = 25°C; GND = 0V CL = 50p F; VCC = 5V VI = 0V or VCC VO = 0V or VCC; 3-State Outputs disabled; VCC = 5.5V Outputs LOW; VCC =...
