The SN74LVCH245ANS from Texas Instruments is a low-voltage non-inverting transceiver from the 74LVCH logic family. It provides a single channel of bidirectional data flow with 3-State outputs for bus isolation. Operating from 1.65V to 3.6V, it supports 1.8V, 2.5V, and 3.3V logic levels, with 24mA output drive capability. The device features bus-hold inputs to prevent floating lines, reducing external component requirements. With a temperature range of -40°C to 125°C, it is suitable for automotive and industrial applications. Packaged in a 20-SOIC, this transceiver is ideal for level shifting, bus buffering, and bidirectional data routing.
- Wide 1.65V to 3.6V Supply Range: Compatible with multiple low-voltage standards, simplifying mixed-voltage design.
- Bus-Hold Inputs: Prevents floating inputs without external resistors, saving board space.
- High 24mA Drive: Ensures robust signal transmission on low-voltage buses.
- Extended Temperature Range: Reliable operation from -40°C to 125°C for harsh environments.
FPGA/CPLD Interface Buffering
In programmable logic designs, this transceiver buffers bidirectional data between FPGAs and external memory or peripherals, ensuring signal integrity at 3.3V.
Level Shifting for 1.8V to 3.3V Systems
With a 1.65V minimum supply, it can translate signals between 1.8V and 3.3V logic, enabling communication between low-voltage sensors and standard logic.
Bus Isolation in Multi-Processor Systems
The 3-State outputs allow the transceiver to be disabled, preventing bus contention when multiple processors share a common data bus.
Memory Card Interface
For SD or MMC card interfaces, this transceiver provides bidirectional buffering with 24mA drive, ensuring reliable data transfer at 3.3V.
Automotive Infotainment Systems
In automotive electronics, the -40°C to 125°C range and robust drive make it suitable for infotainment bus interfaces.
