The 74AC245P is a high-speed CMOS octal bus transceiver manufactured by Toshiba (TOS). Below are the factual specifications, descriptions, and features:

Manufacturer:

Toshiba (TOS)

Description:

The 74AC245P is an 8-bit bidirectional transceiver with 3-state outputs, designed for asynchronous communication between data buses. It allows data transmission in both directions (A to B or B to A) controlled by the Direction (DIR) pin. The Output Enable (OE) pin controls the outputs, allowing them to be placed in a high-impedance state.

Key Features:

• Logic Family: 74AC (Advanced CMOS)
• Supply Voltage Range: 2.0V to 6.0V
• High-Speed Operation:
• tPD (Propagation Delay): 5.5ns (max) at 5V
• Bidirectional Data Flow: Controlled by DIR pin
• 3-State Outputs: Allows bus isolation via OE pin
• Output Drive Capability: ±24mA
• Low Power Consumption:
• ICC (Static Current): 4μA (max)
• Wide Operating Temperature Range: -40°C to +85°C
• Package Type: DIP-20 (Plastic Dual In-Line Package)

Applications:

• Bus interfacing in microprocessors/microcontrollers
• Data communication systems
• Buffering and signal direction control

Pin Configuration (DIP-20):

• A0-A7: Side A Data Bus
• B0-B7: Side B Data Bus
• DIR: Direction Control (High: A→B, Low: B→A)
• OE: Output Enable (Active Low)
