H157D1

The H157D1 from STMicroelectronics is a specialized transistor designed for applications where noise immunity is critical. As part of the High Level Logic (HLL) H100 Series, it is engineered for environments prone to electrical noise hazards. This component family includes a comprehensive range of gates, flip-flops, counters, decoders, and level converters, making it versatile for various digital circuit designs.

The H157D1 is specified as RoHS3 Compliant, indicating adherence to restrictions on hazardous substances. It also has a Moisture Sensitivity Level (MSL) of 1 Unlimited, meaning it requires no special handling regarding humidity. The REACH status is listed as Unaffected. While specific electrical characteristics like operating voltage and temperature are not detailed in the available data, its design as a high threshold logic component suggests suitability for robust industrial or noisy environments.

This transistor is part of a broader family of integrated circuits from SGS-ATES (now part of STMicroelectronics) designed for high noise immunity. The H100 series aims to provide reliable operation in challenging conditions. Further details on its specific applications and performance parameters would typically be found in the manufacturer's datasheet.
