The 74F545 is an 8-bit, 3-State, high speed transceiver. It provides bidirectional drive for the bus-oriented microprocessor and digital communications systems. Straight through bidirectional transceivers are featured, with 24mA bus drive capability on the A ports and 64mA bus drive capability on the B ports. One input, Transmit/Receive (T/R) determines the .
• High impedance NPN base inputs for reduced loading
(70µA in High and Low states) output

• 8-bit bidirectional data flow reduces system package count
• 3-State inputs/outputs for interfacing with bus oriented systems
• 24mA and 64mA bus drive capability on A and B ports,
respectively
• Transmit/Receive and Output Enable simplify control logic
