74ABT374A
Octal D-type flip-flop; positive-edge trigger; 3-state
Rev. 2 — 18 December 2012
Product data sheet
1. General description
The 74ABT374A high-performance BiCMOS device combines low static and dynamic
power dissipation with high speed and high output drive.
The 74ABT374A is an 8-bit, edge triggered register coupled to eight 3-state output
buffers. The two sections of the device are controlled independently by the clock input
(CP) and output enable input (OE) control gates.
The register is fully edge-triggered. The state of each D input, one set-up time before the
LOW-to-HIGH clock transition, is transferred to the corresponding flip-flop’s Q output.
The 3-state output buffers are designed to drive heavily loaded 3-state buses, MOS
memories, or MOS microprocessors. The active LOW output enable (OE) controls all
eight 3-state buffers independent of the clock operation.
When OE is LOW, the stored data appears at the outputs. When OE is HIGH, the outputs
are in the high-impedance “OFF” state, which means they will neither drive nor load the
bus.
