HD74ALVC162244

16-bit Buffer / Driver with 3-state Outputs

ADE-205-204 (Z)

Preliminary

1st. Edition

January 1998

Description

The HD74ALVC162244 is designed specifically to improve both 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 OE

(active-low output-enable) inputs.

To ensure the high impedance state during power up or power down, OE should be tied to VCC through a

pullup resistor; the minimum value of the resistor is determined by the current sinking capability of the

driver.

All outputs, which are designed to sink up to 12 mA, include equivalent 26 Ω resistors to reduce overshoot

and undreshoot.

Features

• VCC = 2.3 V to 3.6 V

• Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C)

• Typical VOH undershoot > 2.0 V (@VCC = 3.3 V, Ta = 25°C)

• High output current ±12 mA (@VCC = 3.0 V)

• All outputs have equivalent 26 Ω series resistors, so no external resistors are required
