TC7SB3157DL6X,(S2E

Overview

The TC7SB3157DL6X is a high-speed CMOS single 1-of-2 multiplexer/demultiplexer manufactured by Toshiba. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an operating temperature from -40 °C to +85 °C. The device features a typical ON resistance of 4 Ω at 4.5 V and a switch ON capacitance of 15 pF at 5.0 V. Propagation delay times are specified with maximum values ranging from 4 ns to 16 ns depending on the supply voltage.

Feature Summary

• Single-channel 1-of-2 multiplexer/demultiplexer functionality controlled by a select input
• Low ON resistance enabling minimal propagation delay for high-speed connections
• Input protection circuits designed against static discharge

Applications

• High-speed data routing in digital systems
• Signal path selection in low-voltage logic circuits
• Multiplexing applications requiring low insertion loss

Procurement Notes

Verify the specific package designation MP6D matches the required footprint, as this differs from standard SSOP variants. Confirm that the operating environment stays within the -40 °C to +85 °C range to ensure performance stability. Ensure unused control inputs are tied to VCC or GND during design implementation to prevent undefined states.

Selection Notes

Select this component when a single-channel analog or digital switch is needed with low ON resistance and wide voltage compatibility. It is suitable for designs requiring operation down to 1.65 V while maintaining fast switching speeds. Consider the MP6D package dimensions if space constraints are critical compared to larger packages like SSOP-6.

Part Context

This device belongs to the TC7SB series of CMOS digital integrated circuits. It functions as a silicon monolithic component produced starting in June 2017. The part serves as a compact solution for signal routing in portable and battery-operated devices due to its low power consumption and wide operating voltage range.

Replacement Considerations

Check datasheets for other Toshiba SB series switches or equivalent parts from other manufacturers offering similar 1.65V–5.5V operation and MP6D packaging. Verify pinout compatibility and electrical parameters such as RON and CI/O before substitution.
