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