72V70800TFG

Signal Switches, Multiplexers, Decoders Overview

The Renesas 72V70800TFG is a non-blocking digital Time Slot Interchanger (TSI) designed for high-capacity switching applications. It provides a switching capacity of 512 x 512 channels at a serial bit rate of 8.192 Mbps. The device operates on a single 3.3V power supply with 5V tolerant inputs and supports an operating temperature range from -40°C to +85°C. Packaged in a 64-pin Thin Plastic Quad Flatpack (TQFP), it accepts four serial data streams and features programmable stream and channel control, processor mode, input offset delay, and high-impedance output control.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific suffix 'TFG' against the manufacturer's current datasheet to confirm package type and RoHS compliance status. Check for any Product Change Notices (PCN) regarding lead material or assembly site changes. Confirm availability through authorized distributors as standard stock levels may vary. Ensure the design-in process accounts for the 64-pin TQFP footprint dimensions and moisture sensitivity level requirements during storage and handling.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a fixed 512 x 512 channel capacity is required for non-blocking digital switching. It is suitable for designs needing 3.3V operation with 5V tolerant I/O interfaces. Consider the 64-pin TQFP package if space constraints align with its 10.0 x 10.0 mm dimensions. Evaluate the need for processor-mode control and per-channel delay programming before choosing over simpler bus switches.
