Translators, Level Shifters

SN74LVC4245APWT Description

The SN74LVC4245APWT from Texas Instruments is a high-performance, bidirectional voltage-level translator designed for seamless interfacing between systems operating at different voltage levels. This 8-bit, non-inverting translator features dual supply rails (VCCA: 4.5V to 5.5V, VCCB: 2.7V to 3.6V), enabling robust signal conversion between 5V and 3.3V logic families. Packaged in a compact 24-pin TSSOP (Thin Shrink Small Outline Package) with tape-and-reel (TR) delivery, it is optimized for space-constrained, high-density PCB designs. The device adheres to RoHS3 and REACH compliance standards, ensuring environmental and regulatory suitability for global markets.

SN74LVC4245APWT Features

• Bidirectional Voltage Translation: Supports seamless data flow between mixed-voltage systems (e.g., 5V MCUs to 3.3V peripherals).
• Wide Operating Range: Dual-supply architecture (VCCA: 4.5–5.5V, VCCB: 2.7–3.6V) accommodates diverse logic levels.
• High-Speed Performance: Low propagation delay and support for fast-switching applications.
• Robust ESD Protection: Enhanced electrostatic discharge (ESD) resilience per industry standards.
• Low Power Consumption: Optimized for energy-sensitive designs.
• Industrial-Grade Reliability: MSL 1 (Unlimited) moisture sensitivity ensures long shelf life and handling ease.

SN74LVC4245APWT Applications

• Mixed-Voltage Systems: Ideal for bridging 5V legacy systems with modern 3.3V components (e.g., microcontrollers, sensors).
• Communication Interfaces: Enables voltage compatibility in UART, SPI, and I2C buses.
• Embedded Systems: Used in industrial automation, IoT devices, and consumer electronics.
• Automotive Electronics: Suitable for infotainment and control modules requiring level shifting.
