IDT74LVCH162244A

DESCRIPTION:

The LVCH162244A 16-bit buffer/driver is built using advanced dual

metal CMOS technology. The LVCH162244A is designed specifically to

improve both the performance and density of 3-state memory address

drivers, clock drivers, and bus-oriented receivers and transmitters. The

Thisdeviceprovidestrueoutputsandsymmetricalactive-lowoutput-enable

(OE) inputs.

All pins of this 16-bit buffer/driver can be driven from either 3.3V or 5V

devices. This feature allows the use of this device as a translator in a mixed

3.3V/5V supply system.

The LVCH162244A has series resistors in the device output structure

which will significantly reduce line noise when used with light loads. This

driver has been developed to drive ±12mA at the designated threshold

levels.

The LVCH162244A has “bus-hold” which retains the inputs’ last state

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

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