74LVTH322373
Low Voltage 32-Bit Transparent Latch
with 3-STATE Outputs
and 25
Series Resistors in the Outputs
General Description
The LVT322373 and LVTH322373 contain thirty-two non-
inverting latches with 3-STATE outputs and are 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 LVTH322373 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) V
CC
applications, but with the capability to provide a TTL inter-
face to a 5V environment. The LVT322373 and
LVTH322373 are fabricated with an advanced BiCMOS
technology to achieve high speed operation similar to 5V
ABT while maintaining a low power dissipation.
