Description:

The HC245 is an octal bus transceiver designed for bidirectional communication between data buses. It features 3-state outputs that allow multiple devices to share a common bus without interference. The direction of data flow is controlled by the DIR (Direction) pin, while the OE (Output Enable) pin enables/disables the outputs.

Features:

• Bidirectional Data Flow: Controlled by DIR pin.
• 3-State Outputs: Allows bus sharing.
• Wide Operating Voltage: 2V to 6V.
• High Noise Immunity: CMOS technology.
• Low Power Consumption: Typical ICC of 80µA.
• Balanced Propagation Delays: Ensures signal integrity.
• ESD Protection: Exceeds 2000V (HBM).
