TISN74LVC8T245
Overview
The SN74LVC8T245 is an 8-bit dual-supply bus transceiver that enables bidirectional voltage-level translation. It features independent configurable power supplies for each port, allowing seamless communication between devices operating at different voltage levels, from 1.65V to 5.5V. This device supports partial-power-down mode operation through its Ioff feature, making it suitable for low-power applications.
Why Choose This Part
This transceiver offers robust ESD protection with 4000-V HBM and 1000-V CDM ratings, enhancing reliability in harsh environments. Its fully configurable dual-rail design and wide supply voltage range (1.65V to 5.5V) provide excellent flexibility for designers working with mixed-voltage systems. The Ioff feature supports partial-power-down mode, contributing to energy efficiency.
