• Manufacturer Part Number: 74vcx32374
• Description: Low Voltage 32-bit D-type Flip-flops With 3.6v Tolerant Inputs And Outputs
• Manufacturer: Fairchild Semiconductor

Functional Description
The 74VCX32374 consists of thirty-two 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 32-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
