UART transceivers for flexible serial communication

Simplify UART ports expansion in your design

Expand serial communications functionality or increase your system's port count with our portfolio of discrete  universal asynchronous receiver/transmitter (UART) transceivers. These devices feature various channel counts, baud rates and first-in, first out (FIFO) depths.

Flexible solutions

Discrete UART solutions provide flexible baud rates, lower current consumption and programmable features

Deeper FIFO memory

First-in, first-out memory up to 64 bytes lets you offload data from an MCU, freeing up valuable processing bandwidth

Multiple channel-count options

Single, dual- and quad-channel offerings to meet varying needs of multiple applications

Featured UART devices


Dual-channel UART with 64-byte FIFOs, automatic hardware and software flow control, and data rates up to 3 Mbps


Four-channel UART with 16-byte FIFOs, enhanced features, and data rates up to 1 Mbps


Serial infrared (SIR) encoder and decoder that encodes and decodes serial data in conformance with the IrDA specification
