SN74AHC1G14QDBVRQ1

Overview

The SN74AHC1G14QDBVRQ1 is an automotive-grade single Schmitt-trigger inverter gate from Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and supports an operating temperature range of -40°C to +125°C. The device features low power consumption with a maximum static current of 10 µA and provides ±8 mA output drive capability at 5 V. It includes balanced CMOS push-pull outputs and exhibits latch-up performance exceeding 250 mA per JESD 17 standards.

Feature Summary

• AEC-Q100 qualified for automotive applications with specified temperature grades and ESD classification levels.
• Schmitt-trigger input architecture providing distinct positive-going and negative-going threshold voltages for noise tolerance.
• Balanced CMOS push-pull outputs capable of sourcing and sinking similar currents for fast signal transitions.

Applications

• Synchronizing inverted clock inputs
• Debouncing mechanical switches
• Inverting digital signals

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the Q1 series is available in both SOT-23 (DBV) and SC-70 (DCK) configurations. Confirm that the selected variant meets the thermal and electrical requirements for the intended automotive environment. Ensure compliance with RoHS directives and check for any recent documentation updates regarding pin functions or packaging changes before finalizing procurement.

Selection Notes

Select this component when a single-channel inverter with hysteresis is required for noisy environments or slow-rising signals. The AHC technology offers a balance between speed and power consumption suitable for various logic families. Consider the specific package dimensions if space constraints exist, noting the differences between the DBV and DCK footprints. Verify that the load capacitance does not exceed recommended limits to maintain switching performance.

Part Context

This part belongs to the SN74AHC1Gxx-Q1 family of automotive single-gate logic devices. It shares the AHC high-speed CMOS process with other members like the NAND and AND gates in the same series. The 'Q1' designation indicates qualification for automotive use, while the 'DBVR' suffix specifies the SOT-23 package and tape-and-reel shipping method.
