The 74HC245AP is an octal bus transceiver manufactured by TOSHIBA. Below are its key specifications, descriptions, and features:
Specifications:
- Logic Family: 74HC (High-Speed CMOS)
- Function: Octal Bus Transceiver (3-State)
- Supply Voltage Range (VCC): 2V to 6V
- Input Voltage Range (VI): 0V to VCC
- Operating Temperature Range: -40°C to +85°C
- Output Current (IO): ±7mA at VCC = 4.5V
- Propagation Delay (tpd): 12ns (typical at VCC = 4.5V)
- Package: 20-pin DIP (Plastic)
Descriptions:
- The 74HC245AP is an octal bidirectional transceiver with 3-state outputs.
- It allows data transmission between two buses in either direction, controlled by the Direction (DIR) input.
- The Output Enable (OE) pin enables/disables the outputs.
- Compatible with TTL levels when operating at 5V.
Features:
- Bidirectional Data Flow: Controlled by DIR pin.
- 3-State Outputs: Allows bus isolation when disabled.
- High-Speed Operation: Optimized for fast data transfer.
- Low Power Consumption: CMOS technology ensures low static power dissipation.
- Wide Operating Voltage Range: Supports 2V to 6V operation.
- TTL-Compatible Inputs: Works with TTL logic levels at 5V supply.
This IC is commonly used in bus interfacing, data buffering, and bidirectional communication in digital systems.
