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 .EATURES:

• Balanced Output Drivers: ±12mA

• Low switching noise
