PI74VCX16373

16-Bit Transparent D-Type Latch

with 3-State Outputs

Product Features

Product Description

• The PI74VCX Family is designed for low voltage

Pericom Semiconductors PI74VCX series of logic circuits are

produced in the Companys advanced 0.35 micron CMOS

technology, achieving industry leading speed.

operation, V

= 1.8V to 3.6V

• 3.6V I/O Tolerant Inputs and Outputs

• Supports Live Insertion

The PI74VCX16373 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.

• Balanced Drive, ±24mA

• Uses patented Noise Reduction Circuitry

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

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.

1OE

The PI74VCX family is I/O Tolerant, allowing it to operate in

mixed 1.8V/3.6V systems.
