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:
