The 74HC245PW,118 is a high-speed CMOS octal bus transceiver designed by Nexperia. It is part of the 74HC family of logic devices, which are known for their high-speed performance and low power consumption. Here’s a detailed description of its features and specifications:
General Description:
The 74HC245 is an octal transceiver that allows for bidirectional data transfer between two buses. It is particularly useful in applications where data needs to be transmitted in both directions, such as in microprocessor and microcontroller interfacing. The device can operate in a variety of logic levels, making it versatile for different digital systems.
Key Features:
- Bus Transceiver: The device can transmit data in both directions, making it suitable for applications requiring bidirectional communication.
- High-Speed Operation: The 74HC245 operates at high speeds, with a maximum propagation delay of around 15 ns at a supply voltage of 5V, making it suitable for fast data transfer applications.
- Wide Supply Voltage Range: It operates with a supply voltage range of 2V to 6V, allowing it to be used in various electronic systems.
- Low Power Consumption: The device features low static and dynamic power consumption, which is beneficial for battery-operated devices.
- Tri-State Outputs: The outputs can be placed in a high-impedance state, allowing multiple devices to share the same bus without interference.
- Control Pins: The device includes control pins (DIR and OE) that manage the direction of data flow and enable/disable the outputs, respectively.
Pin Configuration:
The 74HC245 is typically available in a 20-pin Dual In-line Package (DIP) or a surface-mount package. The pin configuration includes:
- A1 to A8: Data inputs for one bus.
- B1 to B8: Data outputs for the other bus.
- DIR: Direction control pin that determines the data flow direction.
- OE: Output enable pin that activates the outputs when low.
Electrical Characteristics:
- Input Voltage Levels: The device recognizes standard logic levels, with a minimum high-level input voltage (VIH) of 3.5V at a 5V supply.
- Output Drive Capability: It can drive loads of up to 15 mA, making it suitable for interfacing with other logic devices or driving LEDs.
- Temperature Range: The operating temperature range is typically from -40°C to +125°C, making it suitable for industrial applications.
Applications:
The 74HC245 is widely used in various applications, including:
- Microprocessor and microcontroller interfacing.
- Data bus buffering and isolation.
- Communication between different logic families.
- Peripheral device interfacing in embedded systems.
Conclusion:
The 74HC245PW,118 from Nexperia is a robust and versatile octal bus transceiver that provides high-speed, low-power data transfer capabilities in both directions. Its features make it an essential component in modern digital circuits, particularly in applications requiring efficient data communication between multiple devices.
