Functional Description
The 74VCX162374 consists of sixteen edge-triggered flip-
flops with individual D-type inputs and 3-STATE true out-
puts. The device is byte controlled with each byte function-
ing identically, but independent of the other. The control
pins can be shorted together to obtain full 16-bit operation.
Each clock has a buffered clock and buffered Output
Enable common to all flip-flops within that byte. The
description which follows applies to each byte. Each flip-

flop will store the state of their individual I inputs that meet
the setup and hold time requirements on the LOW-to-HIGH
Clock (CPn) transition. With the Output Enable (OEn) LOW,
the contents of the flip-flops are available at the outputs.
When OEn is HIGH, the outputs go to the high impedance
state. Operations of the OEn input does not affect the state
of the flip-flops.
Byte 1 (0:7)
Byte 2 (8:15)
