74LVC1G157GW,125

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LVC1G157GW,125 is a single 2-input multiplexer housed in a TSSOP6 (SOT363-2) package. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and supports an ambient temperature range of -40 °C to +125 °C. The device features Schmitt-trigger inputs for noise immunity and includes IOFF circuitry to prevent backflow current during partial power-down states. It provides direct interface compatibility with TTL levels and overvoltage tolerant inputs up to 5.5 V.

Signal Switches, Multiplexers, Decoders Feature Summary

• Schmitt-trigger action at all inputs ensures tolerance to slower input rise and fall times.
• IOFF circuitry disables the output to prevent damaging backflow current when powered down.
• Inputs are overvoltage tolerant to 5.5 V, allowing use as translators in mixed 3.3 V and 5 V environments.

Signal Switches, Multiplexers, Decoders Applications

• Translating signals between mixed 3.3 V and 5 V logic environments
• Partial power-down applications requiring backflow current prevention
• Data selection circuits utilizing common select inputs

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the ordering suffix ',125' corresponds to the specified TSSOP6 plastic thin shrink small outline package (SOT363-2). Confirm the component meets the required operating temperature range of -40 °C to +125 °C. Ensure the design accounts for the specific pin configuration where Pin 1 is I1 and Pin 6 is S. Cross-reference the marking code 'YP' for identification.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single-channel data selector is needed within the LVC logic family. It is suitable for designs requiring high noise immunity due to Schmitt-trigger inputs. Consider the TSSOP6 package dimensions if board space is constrained. Verify that the 5.5 V input tolerance aligns with the system's highest signal voltage levels.
