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 (CP) and Output Enable (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鈥檚 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 鈥淥FF鈥?state, which
means they will neither drive nor load the bus.
