74LVT32374 • 74LVTH32374

Low Voltage 32-Bit D-Type Flip-Flop

with 3-STATE Outputs

General Description

The LVT32374 and LVTH32374 contain thirty-two non-

inverting D-type flip-flops with 3-STATE outputs and are

intended for bus oriented applications. The device is byte

controlled. A buffered clock (CP) and Output Enable (OE)

are common to each byte and can be shorted together for

full 32-bit operation.

The LVTH32374 data inputs include bushold, eliminating

the need for external pull-up resistors to hold unused

inputs.

applications, but with the capability to provide a TTL inter-

face to a 5V environment. The LVT32374 and LVTH32374

are fabricated with an advanced BiCMOS technology to

achieve high speed operation similar to 5V ABT while

maintaining a low power dissipation.
