74LVC1G19GW,125

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LVC1G19GW,125 is a single-channel 1-of-2 decoder/demultiplexer housed in a TSSOP6 (SOT363-2) package. It operates on a supply voltage range of 1.65 V to 5.5 V and features Schmitt-trigger inputs for noise immunity. The device includes IOFF circuitry to prevent backflow current during partial power-down states. It supports an operating temperature range from -40 °C to +125 °C.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides true and complement outputs controlled by a common active LOW enable input
• Features Schmitt-trigger action at all inputs to tolerate slower rise and fall times
• Includes IOFF circuitry to disable outputs and prevent damaging backflow current when powered down

Signal Switches, Multiplexers, Decoders Applications

• Mixed 3.3 V and 5 V system environments
• Partial power-down applications requiring backflow protection
• Signal decoding and demultiplexing logic circuits

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature grade. Confirm that the component meets RoHS compliance standards for your region. Ensure the supplier provides valid traceability documentation. Check for any recent Product Change Notifications that may affect specifications or manufacturing locations before finalizing procurement orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single-channel decoder with complementary outputs is required in a minimal footprint. The wide supply voltage range allows direct interfacing with both 3.3 V and 5 V logic families. The inclusion of Schmitt triggers makes it suitable for noisy environments or signals with slow transition times compared to standard CMOS devices.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the Nexperia 74LVC family of low-voltage CMOS logic devices. The '1G' designation indicates a single-function gate within a miniaturized package. The GW suffix specifically identifies the TSSOP6 plastic thin shrink small outline package variant, distinguishing it from other package options like SC-74 or XSON6 available in the same logical series.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct pin-compatible alternatives include the 74LVC1G19GV (SC-74 package) and 74LVC1G19GM (XSON6 package). Verify that the substitute maintains the same TSSOP6 footprint if board space constraints are critical.
