FEATURES:

DESCRIPTION:

DRIVE FEATURES:

• High Output Drivers: ±24mA

• Suitable for Heavy Loads

APPLICATIONS:

This octal transparent D-type latch is built using advanced dual metal

CMOS technology. The ALVCH373 device is particularly suitable for

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

working registers. While the latch-enable (LE) input is high, the Q outputs

follow the data (D) inputs. When LE is taken low, the Q outputs are latched

at the logic 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 the high-impedance state, the outputs neither load nor drive the bus

lines significantly. The high-impedance state and increased drive provide

the capability to drive bus lines without interface or pullup components.

The ALVCH373 has been designed with a ±24mA output driver. This

driver is capable of driving a moderate to heavy load while maintaining

speed performance.

The ALVCH373 has a “bus-hold” which retains the inputs’ last state

whenever the input bus goes to a high impedance. This prevents floating

inputs and eliminates the need for pull-up/down resistors.

• 3.3V high speed systems

• 3.3V and lower voltage computing systems
