SN54ABTH16823, SN74ABTH16823
18-BIT BUS-INTERFACE FLIP-FLOPS
WITH 3-STATE OUTPUTS
SCBS664B – APRIL 1996 – REVISED MAY 1997

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
When V
CC
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.
However, to ensure the high-impedance state above 2.1 V, 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 SN54ABTH16823 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABTH16823 is characterized for operation from –40
°
C to 85
°
C.
