description
These 16-bit 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.
The outputs, which are designed to source or sink up to 12 mA, include 25-
series resistors to reduce overshoot
and undershoot.
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 SN74ABT162540 is available in TI’s shrink small-outline package (DL), which provides twice the I/O pin
count and functionality of standard small-outline packages in the same printed-circuit-board area.
The SN54ABT162540 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT162540 is characterized for operation from –40
°
C to 85
°
C.
