74ABT16244 16-Bit Buffer/Line Driver with 3-STATE Outputs
General Description
The ABT16244 contains sixteen non-inverting buffers with 3-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 3STATE control inputs can be shorted together for 8-bit or 16-bit operation.

Features
s Separate control logic for each nibble s 16-bit version of the ABT244 s Outputs sink capability of 64 mA, source capability of 32 mA s Guaranteed output skew s Guaranteed multiple output switching specifications s Output switching specified for both 50 pF and 250 pF loads s Guaranteed simultaneous switching noise level and dynamic threshold performance 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
