72V71660DRG

Signal Switches, Multiplexers, Decoders Overview

The 72V71660DRG is a Time-Slot Interchange (TSI) digital switch manufactured by Renesas Electronics Corporation. It operates on a single 3V to 3.6V power supply and supports switching capacities ranging from 128x128 to 32Kx32K inputs to multiple outputs. The device features four independent circuits and handles PCM highway rates of 2, 4, 8, or 16 Mbps with 64 I/O lines. It functions as a microprocessor-controlled ST-BUS compatible switch without rate matching capabilities. The component is housed in a 208-BFQFP surface-mount package with dimensions of 28x28 mm and operates within a temperature range of -40°C to 85°C.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify RoHS compliance status carefully, as the non-G suffix variant was previously non-compliant while this G-suffix version meets ROHS3 specifications. Confirm current manufacturing status, as discontinuation notices exist for related devices in the series. Ensure compatibility with existing PCB footprints for the 208-PQFP package before integration into new designs.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when designing systems requiring flexible TSI functionality with microprocessor control. It is appropriate for applications needing support for variable PCM rates and large switching matrices. Consider the 208-pin package constraints and verify that the required switching capacity aligns with the specific 128x128 to 32Kx32K configuration needs of the target system.
