16-bit D-type transparent latch with 5 Volt tolerant
inputs/outputs (3-State)

FEA TURES

•5 volt tolerant inputs/outputs for interfacing with 5V logic

•Wide supply voltage range of 1.2V to 3.6V

•Complies with JEDEC standard no. 8-1A

•CMOS low power consumption

•MULTIBYTE

TM

flow-through standard pin-out architecture

•Low inductance multiple power and ground pins for minimum

noise and ground bounce

•Direct interface with TTL levels

•All data inputs have bus hold (74LVCH167373A only)

•High impedance when V

DESCRIPTION

The 74LVC(H)16373A is a 16-bit D-type transparent latch featuring
separate D-type inputs for each latch and 3-State outputs for bus
oriented applications. One latch enable (LE) input and one output
enable (OE
either 3.3V or 5V devices. In 3-State operation, outputs can handle
5V. These features allow the use of these devices in a mixed

3.3V/5V environment.
The 74LVC(H)16373A consists of 2 sections of eight D-type

transparent latches with 3-State true outputs. When LE is HIGH,
data at the Dn inputs enter the latches. In this condition the latches
are transparent, i.e., a latch output will change each time its
corresponding D-input changes.

When LE is LOW the latches store the information that was present
at the D-inputs a set-up time preceding the HIGH-to-LOW transition
of LE. When OE
available at the outputs. When OE
high impedance OFF-state. Operation of the OE
affect the state of the latches.

The 74LVCH16373A bus hold data inputs eliminates the need for
external pull up resistors to hold unused inputs.
