18-bit Buffers / Drivers with 3-state Outputs

ADE-205-172A (Z)

2nd. Edition

December 1999

Description

The HD74ALVCH16825 improves the performance and density of 3-state memory address drivers, clock

drivers, and bus-oriented receivers and transmitters. The device can be used as two 9-bit buffers or one 18-

bit buffer. It provides true data. The 3-state control gate is a 2-input AND gate with active low inputs so

that if either output enable (OE1 or OE2) input is high, all nine affected outputs are in the high impedance

state. Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.

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 ±24 mA (@VCC = 3.0 V)

• Bus hold on data inputs eliminates the need for external pullup / pulldown resistors
