PI74ALVCH16373

16-Bit Transparent D-Type Latch

with 3-STATE Outputs

Product Features

Product Description

Pericom Semiconductor’s PI74ALVCH series of logic circuits are

produced in the Company’s advanced 0.5 micron CMOS

technology, achieving industry leading speed.

• PI74ALVCH16373 is designed for low voltage operation

• V = 2.3V to 3.6V

• Hysteresis on all inputs

This 16-bit transparent D-type latch is designed for 2.3V to 3.6V

operation.

< 0.8V at V = 3.3V, T = 25°C

The PI74ALVCH16373 is particularly suitable for implementing

buffer registers, I/O ports, bidirectional bus drivers, and working

registers. This device can be used as two 8-bit latches or one 16-bit

latch. When the Latch Enable (LE) input is HIGH, the Q outputs

follow the (D) inputs. When LE is taken LOW, the Q outputs are

latched at the levels set up at the D inputs.

< 2.0V at V = 3.3V, T = 25°C

• Bus Hold retains last active bus state during 3-STATE,

eliminating the need for external pullup resistors

• Industrial operation at –40°C to +85°C

• Packages available:

A buffered Output Enable (OE) input can be used to place the

eight outputs in either a normal logic state (high or low logic

levels) or a high-impedance state in which the outputs neither

and the increased drive provide the capability to drive bus lines

without need for interface or pullup components. OE does not

affect internal operations of the latch. Old data can be retained

or new data can be entered while the outputs are in the high

impedance state.

To ensure the high impedance state during power up or power

down, OE should be tied to V through a pullup resistor; the
