74LVTH162374
Low Voltage 16-Bit D-Type Flip-Flop
with 3-STATE Outputs
and 25G58 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 25c58 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.
Features
a73 Input and output interface capability to systems at
5V V
CC
