  • Power-up reset
  • Multiple VCC and GND pins minimize switching noise
  • Independent registers for A and B buses
  • Output capability: +64mA/–32mA
  • Latch-up protection exceeds 500mA per Jedec Std 17

DESCRIPTION

The 74ABT16952 high-performance BiCMOS device combines low static and dynamic power dissipation with high speed and high output drive. 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 (nCPXX) provided that the Clock Enable (nCEXX ) is Low. The data is then present at the 3-State output buffers, but is only accessible when the Output Enable (nOEXX ) 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.
