SN74AHC1G14DBVRG4

Overview

The SN74AHC1G14DBVRG4 is a single-channel inverter from the Texas Instruments SN74AHC1Gxx family, featuring Schmitt-trigger inputs for noise immunity. It operates within a supply voltage range of 2V to 5.5V and utilizes CMOS technology. The device is housed in a SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +125°C. Key electrical characteristics include a maximum low-level output current of 8mA and a high-level output current of -8mA. It complies with RoHS standards and carries the G4 suffix indicating lead-free construction.

Feature Summary

• Schmitt-trigger input functionality provides defined thresholds to filter noise and ensure clean signal transitions.
• Wide supply voltage operation supports compatibility across various logic families and power domains.
• Over-voltage tolerant inputs allow safe interfacing with higher voltage signals without external level shifting.

Applications

• Signal conditioning for noisy digital environments requiring hysteresis
• Wave shaping of slow-rise or slow-fall time signals
• Oscillator circuits utilizing RC timing networks

Procurement Notes

Verify the complete part number including the G4 suffix to confirm lead-free compliance and specific manufacturing revisions. Confirm the SOT-23-5 package type matches your PCB footprint requirements. Ensure the operating temperature range meets your application's environmental specifications. Cross-reference the datasheet revision date to verify any recent parameter updates or design changes before finalizing procurement.

Selection Notes

Select this component when a single inverting gate with noise immunity is required in a minimal footprint. The Schmitt trigger feature distinguishes it from standard inverters like the SN74AHC1G04, making it suitable for applications with degraded signal integrity. Consider the 8mA drive strength for load requirements and verify that the 2V to 5.5V supply range aligns with the system power architecture.

Part Context

This device belongs to the SN74AHC1Gxx series of ultra-small single-gate logic ICs. The AHC (Advanced High-Speed CMOS) technology offers performance comparable to LS-TTL but with lower power consumption. The DBVR suffix specifically denotes the SOT-23-5 tape-and-reel packaging format used for automated surface-mount assembly processes.

Replacement Considerations

SN74AHC1G14DBVT serves as a cut-tape alternative to the reel-packaged DBVR variant. SN74AHC1G14DBVRE4 is a previous generation version; verify pinout and electrical parameters against the latest datasheet before substitution. Other single-inverter Schmitt trigger devices from different manufacturers may require verification of voltage levels and package dimensions.
