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
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) V
CC
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.
