Product specification

74AVC16244

FEATURES

• Wide supply voltage range from 1.2 to 3.6 V

• Complies with JEDEC standard no. 8-1A/5/7

• CMOS low power consumption

• Input/output tolerant up to 3.6 V

• Dynamic Controlled Output (DCO) circuit dynamically

changes output impedance, resulting in noise reduction

without speed degradation

• Low inductance multiple power and ground pins for

minimum noise and ground bounce

• Power off disables 74AVC16244 outputs, permitting live

insertion.

DESCRIPTION

The 74AVC16244 is a 16-bit non-inverting buffer/line

driver with 3-state outputs. This device can be used as four

4-bit buffers, two 8-bit buffers or one 16-bit buffer.

The 3-state outputs are controlled by the output enable

inputs nOE. A HIGH level on input nOE causes the outputs

to assume a high-impedance OFF-state.

This product is designed to have an extremely fast

propagation delay and a minimum amount of power

consumption.

To ensure the high-impedance output state during

power-up or power-down, input nOE should be tied to VCC

through a pull-up resistor (live insertion).

A DCO circuitry is implemented to support termination line

drive during transient (see Figs 1 and 2).
