74LVTH322374

Low Voltage 32-Bit D-Type Flip-Flop

with 3-STATE Outputs

and 25â¦ 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 25â¦ series

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) VCC

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.

Features

s Input and output interface capability to systems at

5V VCC

s Bushold data inputs eliminate the need for external pull-

up resistors to hold unused inputs

s Live insertion/extraction permitted

s Power Up/Power Down high impedance provides glitch-

free bus loading

s Outputs include equivalent series resistance of 25â¦ to

make external termination resistors unnecessary and

reduce overshoot and undershoot

s ESD performance:

Human-body model > 2000V

Machine model > 200V

Charged-device model > 1000V

s Packaged in plastic Fine-Pitch Ball Grid Array (FBGA)
