74LVTH322374

Low Voltage 32-Bit D-Type Flip-Flop

with 3-STATE Outputs

and 25 Series Resistors in the Outputs (Preliminary)

General Description

The LVTH322374 contains thirty-two non-inverting D-type

flip-flops with 3-STATE outputs and is intended for bus ori-

ented applications. The device is byte controlled. A buff-

ered clock (CP) and Output Enable (OE) are common to

each byte and can be shorted together for full 32-bit opera-

tion.

The LVTH322374 is designed with equivalent 25

resistance in both the HIGH and LOW states of the output.

This design reduces line noise in applications such as

memory address drivers, clock drivers, and bus transceiv-

ers/transmitters.

The LVTH322374 data inputs include bushold, eliminating

the need for external pull-up resistors to hold unused

inputs.

These flip-flops are designed for low voltage (3.3V) V

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

face to a 5V environment. The LVTH322374 is fabricated

with an advanced BiCMOS technology to achieve high

speed operation similar to 5V ABT while maintaining a low

power dissipation.
