Description

The 74HC646 integrates an octal bus transceiver with an 8-bit register. It facilitates bidirectional communication between two buses, allowing data to be transferred or stored as needed. The IC can act as a buffer, transceiver, or register, depending on the control inputs.

Features

  • Octal Bus Transceiver: Facilitates 8-bit bidirectional data transfer between two buses.
  • 8-Bit Register: Allows temporary storage of data during the transfer process.
  • Three-State Outputs: The outputs can be set to a high-impedance state, enabling multiple devices to share the same bus lines without interference.
  • Bidirectional Data Flow: Data can be transferred from A to B or B to A depending on the control signals.
  • Latch Capability: Data can be latched into the register, maintaining it for use in subsequent operations.
  • CMOS Technology: Ensures high speed and low power consumption, typical of the 74HC family.

Specifications

  • Logic Family: HC (High-Speed CMOS)
  • Number of Bits: 8 bits for both transceiver and register
  • Operating Voltage: 2V to 6V
  • Max Clock Frequency: Typically up to 50 MHz at 5V
  • Input Compatibility: Compatible with both CMOS and TTL logic levels
  • Output Drive Capability: Can source or sink up to 4 mA at 5V
  • Pin Configuration: DIP-24 package, providing easy integration with standard PCBs
  • Temperature Range: -40°C to +85°C (suitable for industrial applications)
