54ABT16244
16-Bit Buffer/Line Driver with TRI-STATE® Outputs
General Description
The ’ABT16244 contains sixteen non-inverting buffers with
TRI-STATE outputs designed to be employed as a memory
and address driver, clock driver, or bus oriented transmitter/
receiver. The device is nibble controlled. Individual
TRI-STATE control inputs can be shorted together for 8-bit or
16-bit operation.
Features
n Separate control logic for each nibble
n 16-bit version of the ’ABT244
n Outputs sink capability of 48 mA, source capability of
24 mA
n Guaranteed output skew
n Guaranteed multiple output switching specifications
n Output switching specified for both 50 pF and 250 pF
loads
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Guaranteed latchup protection
n High impedance glitch free bus loading during entire
power up and power down cycle
n Non-destructive hot insertion capability
n Standard Microcircuit Drawing (SMD) 5962-9317402
