SN74ALVCH162827

20-BIT BUFFER/DRIVER

WITH 3-STATE OUTPUTS

SCES013H – JULY 1995 – REVISED AUGUST 2004

• Member of the Texas Instruments Widebus™

Family

• Output Ports Have Equivalent 26-Ω Series

Resistors, So No External Resistors Are

Required

• 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)

- 1000-V Charged-Device Model (C101)

This 20-bit noninverting buffer/driver is designed for

1.65-V to 3.6-V V

operation.

The SN74ALVCH162827 is composed of two 10-bit

sections with separate output-enable signals. For

either 10-bit buffer section, the two output-enable

(1OE1 and 1OE2 or 2OE1 and 2OE2) inputs must

both be low for the corresponding Y outputs to be

active. If either output-enable input is high, the

outputs of that 10-bit buffer section are in the

high-impedance state.

The outputs, which are designed to sink up to 12 mA,

include equivalent 26-Ω resistors to reduce overshoot

and undershoot.

To ensure the high-impedance state during power up

or power down, OE should be tied to V

through a

pullup resistor; the minimum value of the resistor is

determined by the current-sinking capability of the

driver.

with the bus-hold circuitry is not recommended.
