74LVC1G3157GF,132

Analog Switches, Multiplexers, Demultiplexers Overview

The Nexperia 74LVC1G3157GF,132 is a single-pole double-throw (SPDT) analog switch manufactured in the GF package variant. It features a digital select input (S), two independent inputs/outputs (Y0 and Y1), and a common input/output (Z). The device operates on a wide supply voltage range from 1.65 V to 5.5 V. Key electrical parameters include a typical ON resistance of 6.5 Ω at VCC = 3.3 V and 6 Ω at VCC = 5 V. It supports a continuous switch current of 32 mA and offers break-before-make switching with high noise immunity.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Supports bidirectional signal transmission for both analog and digital signals across the full supply voltage range.
• Control inputs are overvoltage tolerant up to 5.5 V, enabling direct interfacing with 3.3 V or 5 V logic devices.
• Schmitt-trigger action at control inputs provides tolerance for slower input rise and fall times.
• ESD protection exceeds 2000 V via Human Body Model and 1000 V via Charged Device Model.

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal gating and routing in mixed 3.3 V and 5 V environments
• Chopper stabilization circuits
• Modulation and demodulation in modem applications
• Signal multiplexing for analog-to-digital and digital-to-analog conversion systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific GF package designation against the official ordering information table to ensure correct physical dimensions and pinout compatibility. Confirm that the required operating temperature range aligns with the -40 °C to +125 °C specification provided in the datasheet before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a low ON resistance and rail-to-rail signal handling capability are required within a single SPDT configuration. Ensure the design accommodates the specified maximum continuous switch current of 32 mA and verify that the control logic levels match the overvoltage tolerant input requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the 74LVC1G3157 family of single-channel analog switches. The GF suffix specifically denotes the XSON6 plastic extremely thin small outline package (SOT886). This series is designed for general-purpose signal switching applications requiring CMOS low power dissipation and TTL interface compatibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct replacements must maintain the SPDT topology and compatible package footprint. Verify that alternative sources provide equivalent ON resistance characteristics and ESD protection ratings to ensure functional parity in existing designs.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the function of the Schmitt-trigger action in this device?

The Schmitt-trigger action at the control inputs makes the circuit tolerant of slower input rise and fall times, ensuring reliable switching even with non-ideal control signals.

Can this switch handle signals up to the full supply voltage?

Yes, the device allows amplitude up to VCC (peak) signals to be transmitted along either direction, supporting rail-to-rail signal processing.

How does the break-before-make feature benefit the circuit?

Break-before-make switching ensures that one channel disconnects before the other connects, preventing momentary short circuits between the two independent inputs/outputs during state transitions.
