SN74AHCT1G14DBVT

Overview

The SN74AHCT1G14DBVT is a single Schmitt-trigger inverter gate from the Texas Instruments 74AHCT series. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible inputs. The device provides an output drive capability of ±8 mA at 5 V and exhibits a maximum propagation delay of 8 ns at 5 V with a 50 pF load. It incorporates low static current consumption, typically 1 µA, and offers latch-up performance exceeding 250 mA per JESD 17 standards. The component is housed in a compact SOT-23-5 package.

Feature Summary

• Schmitt-trigger action provides distinct positive and negative input threshold levels for noise immunity
• TTL voltage compatible inputs allow direct interfacing with TTL logic systems
• Low power consumption design minimizes static current draw during operation

Applications

• Signal conditioning for noisy environments requiring hysteresis
• Pulse width modulation signal shaping
• Oscillator circuit timing applications

Procurement Notes

Verify the specific suffix 'VT' indicates tape and reel packaging configuration when sourcing. Confirm the operating temperature range aligns with system requirements, as industrial variants may differ. Ensure the manufacturer part number matches the exact logical function and voltage specifications required for the target application design.

Selection Notes

Select this component when TTL compatibility is required alongside Schmitt-trigger noise rejection capabilities. The AHCT series bridges CMOS performance with TTL input thresholds. Consider the SOT-23-5 package size constraints and the specific 4.5 V to 5.5 V supply voltage window during circuit design integration.

Part Context

This device belongs to the Texas Instruments 74AHCT family of single-gate logic ICs. It shares functional similarities with other single-inverter gates but distinguishes itself through the inclusion of Schmitt-trigger inputs and TTL-compatible voltage levels. The DBVT designation specifies the surface-mount SOT-23-5 package and tape-and-reel delivery format.

Replacement Considerations

SN74AHCT1G14DBVR is a pin-compatible alternative differing primarily in packaging quantity rather than electrical function.
