SN74LVC1G14DBVR

Inverter Gates Overview

The SN74LVC1G14DBVR is a single Schmitt-trigger inverter from Texas Instruments' 74LVC family. It operates within a supply voltage range of 1.65V to 5.5V and supports partial power-down mode. The device features low static current, with a maximum ICC of 10 µA, and provides output drive currents of ±32 mA at 3.3V. Propagation delay is specified as 4.6 ns at 3.3V and 6.5 ns at 2.5V with a 50pF load. It is housed in a SOT-23-5 package and functions across an operating temperature range of -40°C to +125°C.

Inverter Gates Feature Summary

• Schmitt-trigger input action eliminates noise-induced false triggering by providing distinct positive and negative threshold voltages for signal conversion.
• Supports partial power-down mode, allowing I/O pins to remain protected while the device is powered down.
• High noise immunity through latch-up performance exceeding 100 mA per JESD 78 Class II standards.
• Robust ESD protection capabilities exceeding human model, machine model, and charged-device model ratings.

Inverter Gates Applications

• Signal conditioning for noisy digital environments requiring clean square wave outputs.
• Timing circuits such as oscillators and pulse generators utilizing the device's hysteresis characteristics.
• Level shifting between different logic families or voltage domains within mixed-signal systems.

Inverter Gates Procurement Notes

Verify the specific suffix 'DBVR' to confirm the SOT-23-5 package and tape-and-reel packaging format. Ensure compatibility with the target PCB footprint, as pin configurations vary across the 74LVC1G14 series. Cross-reference the manufacturer datasheet for any recent product change notices regarding assembly sites or material composition updates before finalizing procurement.

Inverter Gates Selection Notes

Select this component when a single-channel inverter with high noise immunity is required in a compact surface-mount form factor. The wide supply voltage range allows flexibility in 1.8V, 2.5V, 3.3V, and 5V system designs. Consider the propagation delay specifications against the system clock requirements to ensure timing margins are met under varying load conditions.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74LVC1G14 series of single Schmitt-trigger inverters. The LVC family is characterized by low-voltage operation and high-speed performance suitable for portable applications. The DBVR suffix specifically denotes the SOT-23-5 package type, distinguishing it from other variants like DRYR (SON) or DBVT (SOT-23-5 with different reel options).

Inverter Gates Replacement Considerations

Direct functional equivalents include the SN74LVC1G14DRYR and SN74LVC1G14DBVT. Verify pinout compatibility and package dimensions before substitution, as physical footprints differ between SON and SOT-23 packages. Electrical parameters such as propagation delay and output drive current should be compared against the original design specifications.
