TC7SB3157CFU,LF(CT

Overview

The TC7SB3157CFU,LF(CT is a single-channel CMOS digital integrated circuit functioning as a 1-of-2 multiplexer or demultiplexer. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an operating temperature range of -40 °C to 125 °C. The device features low on-resistance (typical 4 Ω at 4.5 V) and low ON capacitance (15 pF typical). It utilizes a US6 package with six pins: B2, GND, B1, A, VCC, and S.

Feature Summary

• AEC-Q100 Grade 1 qualified for automotive reliability requirements
• Wide operating temperature range from -40 °C to 125 °C
• Low ON resistance enabling minimal propagation delay time
• All inputs equipped with protection circuits against static discharge

Applications

• Automotive electronic systems requiring high reliability
• High-speed signal routing in consumer electronics
• Data bus switching applications
• Multiplexing/demultiplexing control circuits

Procurement Notes

Verify the specific ordering suffix (CT) to confirm the extended operating temperature range (-40 °C to 125 °C), as other variants may be limited to -40 °C to 85 °C. Ensure compliance with AEC-Q100 Grade 1 requirements if used in automotive contexts. Confirm RoHS compatibility and environmental regulations with the manufacturer before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel, high-speed analog switch or digital multiplexer is required. The wide supply voltage range (1.65 V to 5.5 V) allows compatibility with various logic families. Consider the low ON capacitance for high-frequency signal integrity. Verify that the US6 package fits the PCB layout constraints and that the thermal performance meets the application's power dissipation limits.

Part Context

This part belongs to Toshiba's TC7SB series of CMOS digital integrated circuits. It is designed for applications requiring fast switching speeds and low power consumption. The device integrates a single 1-of-2 multiplexer/demultiplexer function into a compact surface-mount package, suitable for space-constrained designs.

Replacement Considerations

Consult Toshiba sales representatives for direct replacements or cross-references. Ensure any substitute component matches the US6 package dimensions, pinout configuration, and electrical characteristics such as supply voltage range and on-resistance.
