OCTAL BUFFERS/DRIVERS
WITH 3-STATE OUTPUTS
SCBS093L – DECEMBER 1993 – REVISED DECEMBER 2006
The 3-state control gate is a two-input AND gate with active-low inputs so that if either output-enable ( OE1 or
OE2) input is high, all eight outputs are in the high-impedance state.
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.
The SN54ABT541 is characterized for operation over the full military temperature range of –55 ° C to 125 ° C. The
SN74ABT541B is characterized for operation from –40 ° C to 85 ° C.
