PI74ALVTC16373

16-Bit Transparent D-Type Latch

with 3-STATE Outputs

Product Features

Product Description

PI74ALVTC family is designed for low voltage operation,

Pericom Semiconductors PI74ALVTC series of logic circuits are

produced in the Companys advanced 0.35 micron CMOS

technology, achieving industry leading speed.

VDD = 1.8V to 3.6V

Supports Live Insertion

3.6V I/O Tolerant Inputs and Outputs

Bus Hold

The PI74ALVTC16373 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.

High Drive, -32/64mA @ 3.3V

Uses patented noise reduction circuitry

Power-off high impedance inputs and outputs

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 load nor drive

the bus lines significantly. The high-impedance state and the

increased drive provide the capability to drive bus lines without an

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 ouputs are in the high-impedance state.

Logic Block Diagram

To ensure the high-impedance state during power up or power

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

minimum value of the resistor is determined by the current-sinking

capability of the driver.

1LE

The family offers both I/O Tolerant, which allows it to operate in

mixed 1.8/3.6V systems, and Bus Hold, which retains the data

inputs last state whenever the data input goes to high-impedance,

preventing floating inputs and eliminating the need for pullup/

down resistors.
