74AC245P** is a high-speed CMOS octal bus transceiver manufactured by **Toshiba (TOS)**.

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)

This information is based on Toshiba's official datasheet for the 74AC245P. For detailed electrical characteristics and timing diagrams, refer to the manufacturer's documentation.
