description (continued)
A buffered output-control input OC can be used to place the nine outputs in either normal logic state (high or
low level) or a high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus
lines significantly. The high-impedance state and increased drive provide the capability to drive the bus lines
in a bus-organized system without need for interface or pullup components. The output control does not affect
the internal operation of the flip-flops. Old data can be retained or new data can be entered while the outputs
are in the high-impedance state.
The SN54AS’ family is characterized for operation over the full military temperature range of – 55
°C to 125°C.
The SN74AS’ family is characterized for operation from 0
°C to 70°C.
