74LVTH162374
Low Voltage 16-Bit D-Type Flip-Flop
with 3-STATE Outputs
and 25: Series Resistors in the Outputs
General Description
The LVTH162374 contains sixteen 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 16-bit opera-
tion.
The LVTH162374 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 LVTH162374 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 LVTH162374 is fabricated
with an advanced BiCMOS technology to achieve high
speed operation similar to 5V ABT while maintaining a low
power dissipation.
