SN74ALVCH162831
1-BIT TO 4-BIT ADDRESS REGISTER/DRIVER
WITH 3-STATE OUTPUTS
SCES084E AUGUST 1996 REVISED FEBRUARY 1999
4184
POST OFFICE BOX 655303 DALLAS, TEXAS 75265
description (continued)
The outputs, which are designed to sink up to 12 mA, include equivalent 26- 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.
Active bus-hold circuitry is provided to hold unused or floating data inputs at a valid logic level.
The SN74ALVCH162831 is characterized for operation from 40°C to 85°C.
