Description

Pericom Semiconductor’s 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.

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

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

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

capability of the driver.

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

mixed 1.8V/3.6V systems.
