HD74ALVCH162244
16-bit Buffers / Drivers with 3-state Outputs
ADE-205-173A (Z)
Preliminary
2nd. Edition
January 1998
Description
The HD74ALVCH162244 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
active-low output-enable (
OE
) inputs.
To ensure the high impedance state during power up or power down,
OE
should be tied to V
CC
through a
pullup resistor; the minimum value of the resistor is determined by the current sinking capability of the
driver.
Active bus hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
All outputs, which are designed to sink up to 12 mA, include 26
resistors to reduce overshoot and
undershoot.
Features
V
CC
= 2.3 V to 3.6 V
Typical V
OL
ground bounce < 0.8 V (@V
CC
= 3.3 V, Ta = 25°C)
Typical V
OH
undershoot > 2.0 V (@V
CC
= 3.3 V, Ta = 25°C)
High output current ±12 mA (@V
CC
= 3.0 V)
Bus hold on data inputs eliminates the need for external pullup / pulldown resistors
All outputs have equivalent 26
series resistors, so no external resistors are required.
