STMicroelectronics Line Transmitter 3 State Negative 20-Pin SOIC L6374FP

STMicroelectronics L6374FP is a high-performance line transmitter designed for interface applications requiring 3 state negative output drivers. This device employs 74F logic family technology to provide reliable line driving capabilities with differential input types. Packaged in a 20-pin SOIC surface mount casing measuring 13mm in length, 7.6mm in width, and 2.65mm in height, it is compact and suitable for modern electronics manufacturing.

Operating with a supply voltage between 10.8V and 40V, the L6374FP supports industrial temperature ranges from -25°C to 125°C. It offers a maximum propagation delay time of 1.5 milliseconds under specified load conditions and consumes a low supply current of about 1mA, making it power efficient. The device's design includes intelligent high-side driver functions, featuring internal current limiting, thermal shutdown protection, under-voltage lockout with hysteresis, and presettable delay for overcurrent to ensure robust performance and safety.

This line transmitter is intended for industrial, construction, and manufacturing environments where controlled line driving and switching of inductive, resistive, or capacitive loads are necessary. It is ideal for integration in high-side power switch circuits requiring diagnostic outputs for under voltage, over temperature, and over current conditions, enabling preventive maintenance and system protection.

The 20-pin SOIC format allows easy surface mounting onto printed circuit boards, facilitating efficient mass production. Although not meeting automotive standards, it suits a wide range of electronics and power control applications requiring reliable line interface control.
