74LVT373 • 74LVTH373

Low Voltage Octal Transparent Latch

with 3-STATE Outputs

General Description

The LVT373 and LVTH373 consist of eight latches with

3-STATE outputs for bus organized system applications.

The latches appear transparent to the data when Latch

Enable (LE) is HIGH. When LE is LOW, the data satisfying

the input timing requirements is latched. Data appears on

the bus when the Output Enable (OE) is LOW. When OE is

HIGH, the bus output is in a high impedance state.

The LVTH373 data inputs include bushold, eliminating the

need for external pull-up resistors to hold unused inputs.

These octal latches are designed for low-voltage (3.3V)

interface to a 5V environment. The LVT373 and LVTH373

are fabricated with an advanced BiCMOS technology to

achieve high speed operation similar to 5V ABT while

maintaining low power dissipation.
