74LVT16373 • 74LVTH16373

Low Voltage 16-Bit Transparent Latch

with 3-STATE Outputs

General Description

The LVT16373 and LVTH16373 contain sixteen non-invert-

ing 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 LVTH16373 data inputs include bushold, eliminating

the need for external pull-up resistors to hold unused

inputs.

applications, but with the capability to provide a TTL inter-

face to a 5V environment. The LVT16373 and LVTH16373

are fabricated with an advanced BiCMOS technology to

achieve high speed operation similar to 5V ABT while

maintaining a low power dissipation.
