description
The SN54ABT16540 and SN74ABT16540A are
inverting 16-bit buffers/drivers composed of two
8-bit sections with separate output-enable gates.
These buffers and bus drivers provide a
high-performance bus interface for wide data
paths.
The 3-state control gate is a 2-input AND gate with
active-low inputs so that if either output-enable
(OE1 or OE2) input is high, all corresponding
outputs are in the high-impedance state.
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.
The SN54ABT16540 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT16540A is characterized for operation from –40
°
C to 85
