74LVTH162373
Low Voltage 16-Bit Transparent Latch with
3-STATE Outputs and
25: Series Resistors in the Outputs
General Description
The LVTH162373 contains sixteen non-inverting latches
with 3-STATE outputs and is intended for bus oriented
applications. The device is byte controlled. The flip-flops
appear transparent to the data when the Latch Enable (LE)
is HIGH. When LE is LOW, the data that meets the setup
time is latched. Data appears on the bus when the Output
Enable (OE) is LOW. When OE is HIGH, the outputs are in
a high impedance state.
The LVTH162373 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 LVTH162373 data inputs include bushold, eliminating
the need for external pull-up resistors to hold unused
inputs.
These latches are designed for low-voltage (3.3V) VCC
applications, but with the capability to provide a TTL inter-
face to a 5V environment. The LVTH162373 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/Down high impedance provides glitch-free
bus loading
s Outputs include equivalent series resistance of 25: to
make external termination resistors unnecessary and
reduce overshoot and undershoot
s Functionally compatible with the 74 series 16373
s Latch-up performance exceeds 500 mA
s ESD performance:
Human-body model ! 2000V
Machine model ! 200V
Charged-device model ! 1000V

Functional Description
The LVTH162373 contains sixteen D-type latches with 3-STATE standard outputs. The device is byte controlled with each
byte functioning identically, but independent of the other. Control pins can be shorted together to obtain full 16-bit operation.
The following description applies to each byte. When the Latch Enable (LEn) input is HIGH, data on the Dn enters the
latches. In this condition the latches are transparent, i.e, a latch output will change states each time its D input changes.
When LEn is LOW, the latches store information that was present on the D inputs a setup time preceding the HIGH-to-LOW
transition of LEn. The 3-STATE standard outputs are controlled by the Output Enable (OEn) input. When OEn is LOW, the
standard outputs are in the 2-state mode. When OEn is HIGH, the standard outputs are in the high impedance mode but
this does not interfere with entering new data into the latches.
