74ABT162244
16-Bit Buffer/Line Driver with
25Ω Series Resistors in the Outputs
General Description
The ABT162244 contains sixteen non-inverting buffers with
3-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus oriented transmit-
ter/receiver. The device is nibble controlled. Individual 3-
STATE control inputs can be shorted together for 8-bit or
16-bit operation.
The 25Ω series resistors in the outputs reduce ringing and
eliminate the need for external resistors.
Features
s Separate control logic for each nibble
s 16-bit version of the ABT2244
s Guaranteed latchup protection
s High impedance glitch free bus loading during entire
power up and power down cycle
s Non-destructive hot insertion capability
