• Output Drive Capability: 64mA (sink/source)
• High-Level Output Current (Ioh): -3mA
• Low-Level Output Current (Iol): 24mA

Descriptions:

• The 74F623N is an 8-bit bidirectional transceiver designed for asynchronous communication between data buses.
• It features separate control inputs for data flow direction (DIR) and output enable (OE), allowing flexible bus management.
• Compatible with TTL and CMOS logic levels when interfaced properly.

Features:

• Bidirectional Data Flow: Controlled by DIR (Direction) pin.
• Three-State Outputs: High-impedance state when OE (Output Enable) is inactive.
• High-Speed Operation: Optimized for fast data transfer.
• Wide Operating Voltage: Supports standard 5V logic.
• Robust Output Drive: Capable of driving heavily loaded buses.

This IC is commonly used in data communication systems, microprocessor interfaces, and bus-oriented applications.
