(TOP VIEW)

The ′ABT377 are 8-bit positive-edge-triggered

D-type flip-flops with a clock (CLK) input. They are

particularly suitable for implementing buffer and

storage registers, shift registers, and pattern

generators.

18 8D

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

commonclock-enable(CLKEN)inputislow. 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 SN74ABT377 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count

and functionality of standard small-outline packages in less than half the printed-circuit-board area.

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

SN74ABT377 is characterized for operation from –40°C to 85°C.
