IDT72V8980J

Signal Switches, Multiplexers, Decoders Overview

The IDT72V8980J is a 3.3V Time Slot Interchange (TSI) digital switch manufactured by Renesas Electronics. It provides a non-blocking 256 x 256 channel switching matrix designed for telecommunications applications. The device supports ST-BUS® compatibility and features eight RX inputs and eight TX outputs, each handling 32 channels at 64 Kbit/s per serial line. It includes three-state serial outputs and an 8-bit microprocessor interface. The component operates on a single 3.3V power supply with 5V tolerant I/O inputs and is housed in a 44-pin Plastic Leaded Chip Carrier (PLCC) package.
