SN74AHCT1G14DBVR

Overview

The SN74AHCT1G14DBVR is a single Schmitt-trigger inverter gate manufactured by Texas Instruments. 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. Maximum propagation delay is specified as 8 ns at 5 V with a 50 pF load. Quiescent current (ICC) is limited to a maximum of 10 µA. The component is housed in a SOT-23-5 surface-mount package, measuring 2.9 mm in length, 1.6 mm in width, and 1.15 mm in height. It supports an operating temperature range from -40°C to +85°C.

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 sources
• Low quiescent current consumption reduces overall power usage
• Latch-up performance exceeds 250 mA per JESD 78 standards

Applications

• Industrial control systems requiring signal conditioning
• Pulse waveform generation circuits
• Timing pulse width modification applications

Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free manufacturing details directly from the manufacturer's latest datasheet revision. Cross-reference pinout configurations to prevent integration errors during PCB layout and assembly processes.

Selection Notes

Select this component when TTL-level compatibility is required alongside Schmitt-trigger noise filtering capabilities. The SOT-23-5 package offers space efficiency for compact designs. Ensure the application voltage remains strictly within the 4.5 V to 5.5 V range to maintain specified electrical characteristics and timing parameters.
