description

These 8-bit positive-edge-triggered D-type

flip-flops with a clock (CLK) input are particularly

suitable for implementing buffer and storage

registers, shift registers, and pattern generators.

Data (D) input information that meets the setup

time requirements is transferred to the Q outputs

on the positive-going edge of the clock pulse if the

common clock-enable (CLKEN

) input is low.

Clock triggering occurs at a particular voltage

level and is not directly related to the transition

time of the positive-going pulse. When the

buffered clock (CLK) input is at either the high or

low level, the D-input signal has no effect at the

output. The circuits are designed to prevent false

clocking by transitions at CLKEN

The SN54ABT377 is characterized for operation over the full military temperature range of –55°C to 125°C. The

SN74ABT377A is characterized for operation from –40°C to 85°C.
