Quad Tridirectional Bus Transceiver
(with noninverted/inverted 3-state outputs)
Description
These bus transceivers are designed for a synchronous three-way communication between four-line data
buses. They give the designer a choice of selecting inverting, noninverting or a combination of inverting
and noninverting data paths with 3-state outputs.
The S0 and S1 inputs select the bus from which data are to be transferred. The G inputs enable the bus or
buses to which data are to be transferred. The port for any bus selected for input and any other bus not
enabled for output will be at high impedance.
Features
• High Speed Operation
• High Output Current: Fanout of 15 LSTTL Loads
• Wide Operating Voltage: VCC = 2 to 6 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C)
