IDT74ALVCH162244

3.3V CMOS 16-BIT

BUFFER/DRIVER WITH

3-STATE OUTPUTS

AND BUS-HOLD

DESCRIPTION:

This 16-bit buffer/driver is built using advanced dual metal CMOS

technology. The ALVCH162244 is designed specifically to improve the

performance and density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and transmitters. The device can be

used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer. It provides

true outputs and symmetrical active-low output-enable (OE) inputs.

The ALVCH162244 has series resistors in the device output structure

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

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

levels.

The ALVCH162244 has “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.

APPLICATIONS:

• 3.3V high speed systems

• 3.3V and lower voltage computing systems

DRIVE FEATURES:

• Balanced Output Drivers: ±12mA

• Low switching noise
