The
′
ABT162240 is a 16-bit buffer and line driver
designed specifically to improve both the
performance and density of 3-state memory
address drivers, clock drivers, and bus-oriented
receivers and transmitters. The device can be
used as four 4-bit buffers, two 8-bit buffers, or one
16-bit buffer. This device provides inverting
outputs
and
symmetrical
output-enable) inputs.
OE
(active-low
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 SN74ABT162240 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 SN54ABT162240 is characterized for operation over the full military temperature range of –55
°
C to 125
°
C.
The SN74ABT162240 is characterized for operation from –40
°
C to 85
°
C.
