74LVC1G19GV,125

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LVC1G19GV,125 is a single 1-of-2 decoder/demultiplexer housed in a SC-74 (TSOP6) package. It operates within a supply voltage range of 1.65 V to 5.5 V and supports an input voltage up to 5.5 V. The device features Schmitt-trigger inputs for noise immunity and IOFF circuitry for partial power-down protection. Propagation delay ranges from 3.9 ns to 13.1 ns depending on the supply voltage and temperature conditions.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides 1-of-2 decoding or demultiplexing functionality with a common active-low enable input.
• Includes IOFF circuitry that disables outputs to prevent damaging backflow current during power-down states.
• Schmitt-trigger action at all inputs ensures tolerance for slower input rise and fall times.

Signal Switches, Multiplexers, Decoders Applications

• Mixed 3.3 V and 5 V system environments
• Partial power-down applications requiring backflow prevention
• Signal routing and data distribution

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix GV against the required package type SOT457 (SC-74; TSOP6). Confirm the temperature range specification matches the design requirement of -40 °C to +125 °C. Ensure compatibility with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 for the intended operating voltage.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a single-channel decoder or demultiplexer with high noise immunity is required. The wide supply voltage range allows direct interfacing with both 3.3 V and 5 V logic levels. The inclusion of IOFF circuitry makes it suitable for systems where partial power-down modes are utilized to reduce standby power consumption.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the 74LVC family of low-voltage CMOS logic ICs manufactured by Nexperia. The LVC series is designed for applications requiring operation at lower supply voltages while maintaining compatibility with standard logic levels. The 74LVC1G19 specifically addresses signal routing needs within a minimal footprint provided by the SC-74 package.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Check for alternative packages such as TSSOP6 (SOT363-2) or XSON6 variants if pinout compatibility or board space constraints differ. Verify that any substitute maintains the same 1-of-2 decoder functionality and IOFF capabilities.
