DESCRIPTION/ORDERING INFORMATION

This 16-bit edge-triggered D-type flip-flop is designed

for 1.65-V to 3.6-V VCC operation.

The SN74ALVCH162374 is particularly suitable for

implementing buffer registers, I/O ports, bidirectional

bus drivers, and working registers. It can be used as

two 8-bit flip-flops or one 16-bit flip-flop. On the

positive transition of the clock (CLK) input, the Q

outputs of the flip-flop take on the logic levels set up

at the data (D) inputs.

The output-enable (OE) input can be used to place

the eight outputs in either a normal logic state (high

or low logic levels) or a high-impedance state. In the

high-impedance state, the outputs neither load nor

drive the bus lines significantly. The high-impedance

state and the increased drive provide the capability to

drive bus lines without need for interface or pullup

components. OE does not affect internal operations

of the flip-flop. Old data can be retained or new data

can be entered while the outputs are in the

high-impedance state.

The outputs, which are designed to sink up to 12 mA, include equivalent 26-W resistors to reduce overshoot and

undershoot.
