DESCRIPTION

The 74ABT16500C is a high-performance BiCMOS Device which combines low static and dynamic power dissipation with high speed and high output drive.

Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

Two options are available, 74ABT16500C which does not have the bus-hold feature and 74ABTH16500C which incorporates the bus-hold feature.

FEATURES

? 18-bit bidirectional bus interface

? 3-State buffers

? 74ABTH16500C incorporates bus-hold data inputs which

eliminate the need for external pull-up resistors to hold unused

inputs

? Output capability: +64mA/-32mA

? TTL input and output switching levels

? Live insertion/extraction permitted

? Power-up reset

? Power-up 3-State

? Negative edge-triggered clock inputs

? Latch-up protection exceeds 500mA per JEDEC Std 17

? ESD protection exceeds 2000V per MIL STD 883 Method 3015

and 200V per Machine Model

? Flexible operation permits 18 embedded D-type latches or

flip-flops to operate in clocked, transparent, or latched modes.
