SN54ABT16260, SN74ABTH16260
12-BIT TO 24-BIT MULTIPLEXED D-TYPE LATCHES
WITH 3-STATE OUTPUTS

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description (continued)
When VCC 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 VCC 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 SN54ABT16260 is characterized for operation over the full military temperature range of –55
°C to 125°C.
The SN74ABTH16260 is characterized for operation from –40
°C to 85°C.
