• Manufacturer Part Number: 74lcxh16374
• Description: 74lcxh16374 Low Voltage 16-bit D-type Flip-flop With Bushold
• Manufacturer: Fairchild Semiconductor

Functional Description
The LCXH16374 consists of sixteen edge-triggered
flip-flops with individual D-type inputs and 3-STATE true
outputs. The device is byte controlled with each byte func-
tioning identically, but independent of the other. The control
pins can be shorted together to obtain full 16-bit operation.
Each byte 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
