SN74HC241DWG4 Application Field and Working Principle

The SN74HC241DWG4 is a buffered logic integrated circuit (IC) of the 74HC241 family, designed to drive and receive digital signals between two separate systems. The IC offers four buffers and has three different modes of operation, enabling applications in both standard digital logic and transceiver based functions. This article provides an overview of the SN74HC241DWG4’s application field and working principle.

Application Field

The SN74HC241DWG4 is commonly used as a buffer controller and transceiver interface in digital systems. It is specifically designed to drive and receive standard TTL digital signals between two separate systems, such as a microcontroller and an FPGA in embedded systems, or communications links between two PCs on a Local Area Network. The IC also provides reconfigurable logic functions that can be used to implement complicated logic operations.

Physical Characteristics

The SN74HC241DWG4 is a 20-pin DIP package and provides four buffered outputs. The two channel IC is constructed using CMOS technology and is typically interfaced with the 5 Volt TTL logic family. The IC includes four open collector outputs with a maximum sink current of 25mA. The Supply Voltage (VCC) is between 4.5 to 5.5 Volts, and the Input Voltage (VIH) is between 1.5 to 5.5 Volts.

Operation Modes

The SN74HC241DWG4 offers three distinct modes of operation. In the first mode, the IC operates as an open collector driver, allowing it to source or sink digital signals. In the second mode, the IC acts as a logic buffer. This mode enables it to drive digital logic signals between two systems while remaining transparent to data transitions. In the third mode, the IC is reconfigured as a transceiver, allowing it to drive multiple logic signals in both directions.

Working Principle

The SN74HC241DWG4 is a multi-mode buffered logic IC that is commonly used in digital signal, logic buffer and transceiver applications. The IC’s four independent buffered outputs provide the flexibility to connect and drive digital logic signals between two separate systems. Additionally, reconfigurable logic functions offer the ability to implement complicated logic operations. Through its multiple operating modes, the SN74HC241DWG4 has the capability to support a variety of digital signal applications.
