54ABT16374
16-Bit D Flip-Flop with TRI-STATE® Outputs
General Description
The ABT16374 contains sixteen non-inverting D flip-flops
with TRI-STATE outputs and is intended for bus oriented ap-
plications. The device is byte controlled. A buffered clock
(CP) and Output Enable (OE) are common to each byte and
can be shorted together for full 16-bit operation.
Features
n Separate control logic for each byte
n 16-bit version of the ABT374
n Edge-triggered D-type inputs
n Buffered Positive edge-triggered clock
n High impedance glitch free bus loading during entire
power up and power down cycle
n Non-destructive hot insertion capability
n Guaranteed latch-up protection
n Standard Microcircuit Drawing (SMD) 5962-9320101
