SN54ABT16843, SN74ABT16843
18-BIT BUS-INTERFACE D-TYPE LATCHES
WITH 3-STATE OUTPUTS
SCBS223E – OCTOBER 1992 – REVISED MAY 1997

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
OE does not affect the internal operations of the latch. Previously stored data can be retained or new data can
be entered while the outputs are in the high-impedance state.
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.
The SN54ABT16843 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT16843 is characterized for operation from –40
°
C to 85
°
C.
