74LVC1G157GS,132

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LVC1G157GS,132 is a single 2-input multiplexer housed in an XSON6 (SOT1202) package. It operates on a supply voltage range of 1.65 V to 5.5 V with inputs tolerant up to 5.5 V. The device features Schmitt-trigger action for noise immunity and IOFF circuitry for partial power-down protection. It supports output drive currents of ±24 mA at 3.0 V and complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36.

Signal Switches, Multiplexers, Decoders Feature Summary

• Schmitt-trigger inputs provide tolerance for slower rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent backflow current.
• Inputs are overvoltage tolerant up to 5.5 V for mixed-voltage translation.

Signal Switches, Multiplexers, Decoders Applications

• Mixed 3.3 V and 5 V signal translation environments
• Partial power-down applications requiring backflow prevention
• Signal routing in low-power CMOS logic systems

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific SOT1202 (XSON6) package variant matches the design footprint. Confirm that the ordering suffix corresponds to the required tape-and-reel quantity. Ensure the application environment remains within the specified -40 °C to +125 °C temperature range. Validate input voltage levels against the 5.5 V absolute maximum rating.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single-channel 2:1 multiplexing function is required in a minimal footprint. The XSON6 package offers a body size of 1.0 x 1.0 mm. Consider the IOFF feature if the system requires safe operation during partial power-down states. Verify compatibility with the target supply voltage range between 1.65 V and 5.5 V.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the 74LVC series of single-gate logic devices manufactured by Nexperia. The GS suffix specifically denotes the XSON6 package type (SOT1202). Other variants in the family include TSSOP6, SC-74, and different XSON dimensions, all sharing identical logical functionality but differing in physical packaging.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include other 74LVC1G157 variants from Nexperia such as 74LVC1G157GW or 74LVC1G157GM, provided the package footprint is compatible. Cross-manufacturer equivalents must be verified for pinout and electrical characteristics matching the original specification.

Signal Switches, Multiplexers, Decoders FAQ

How does the IOFF circuitry function?

The IOFF circuitry disables the output when the device is powered down, preventing potentially damaging backflow current through the device.

What is the input voltage tolerance?

The inputs are overvoltage tolerant up to 5.5 V, allowing direct interfacing with 5 V devices even when the supply voltage is lower.
