SN74ALVC162831
1-BIT TO 4-BIT ADDRESS REGISTER/DRIVER
WITH 3-STATE OUTPUTS
SCAS605A – APRIL 1998 – REVISED FEBRUARY 1999
4–176
POST OFFICE BOX 655303 • DALLAS, TEXAS 75265
description (continued)
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
CC
through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
The SN74ALVC162831 is characterized for operation from –40°C to 85°C.
