SN74ALVCH16244

16-BIT BUFFER/DRIVER

WITH 3-STATE OUTPUTS

SCES014K – JULY 1995 – REVISED OCTOBER 2005

• Member of the Texas Instruments Widebus™

Family

• Operates From 1.65 V to 3.6 V

• Max t

of 3 ns at 3.3 V

• ± 24-mA Output Drive at 3.3 V

• Bus Hold on Data Inputs Eliminates the Need

for External Pullup/Pulldown Resistors

• Latch-Up Performance Exceeds 250 mA Per

JESD 17

• ESD Protection Exceeds JESD 22

– 2000-V Human-Body Model (A114-A)

– 200-V Machine Model (A115-A)

This 16-bit buffer/driver is designed for 1.65-V to

3.6-V V

operation.

The SN74ALVCH16244 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.

To ensure the high-impedance state during power up

or power down, OE should be tied to V

through a

blank

pullup resistor; the minimum value of the resistor is

blank

determined by the current-sinking capability of the

driver.
