74ABT16244 16-Bit Buffer/
Line Driver with TRI-STATEÉ Outputs
General Description
The ’ABT16244 contains sixteen non-inverting buffers with
TRI-STATE outputs designedtobe employedasa memory
and address driver, clockdriver,orbusoriented transmitter/
receiver. The deviceis nibble controlled. Individual TRI-
STATE control inputscanbe shorted togetherfor 8-bitor
16-bit operation.
Features Separate control logicfor each nibble 16-bit versionofthe ’ABT244 Outputs sink capabilityof64 mA, source capabilityofmA Guaranteed output skew Guaranteed multiple output switching specifications Output switching specifiedfor both50pF and 250pF
loads Guaranteed simultaneous switching noise leveland
dynamic threshold performance Guaranteed latchup protection High impedance glitch free bus loading during entire
powerupand power down cycle Non-destructivehot insertion capability
