SN74AHC1G14DCKJ

Overview

The SN74AHC1G14DCKJ is a single-channel Schmitt-trigger inverter from the Texas Instruments AHC logic family. It operates within a supply voltage range of 2V to 5.5V and supports an operating temperature range of -40°C to +125°C. The device features balanced outputs with a maximum output current of 8mA for both high and low states, while maintaining a maximum static current of 1µA. Propagation delay is specified at 10.6ns when driven at 5V with a 50pF load. It utilizes a 5-SC70 (SOT-353) surface-mount package.

Feature Summary

• Integrates Schmitt-trigger input characteristics to provide noise filtering and hysteresis for clean signal transitions.
• Offers over-voltage tolerant inputs allowing safe operation with signals exceeding the VCC level.
• Provides balanced push-pull outputs capable of driving standard CMOS and TTL loads.

Applications

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

Procurement Notes

Verify the specific suffix 'J' against official manufacturer documentation to confirm its exact meaning regarding tape-and-reel specifications or marking codes. Ensure compatibility with SC-70-5 footprint requirements during PCB layout. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when a single inverter with Schmitt-trigger functionality is required in a minimal footprint. It is suitable for applications needing over-voltage tolerance on inputs without external protection components. Consider propagation delay specifications relative to system clock speeds to ensure timing margins are met under varying voltage conditions.

Part Context

This part belongs to the SN74AHC1Gxx series of single-gate logic devices designed for space-constrained designs. It shares functional similarities with other members like the SN74AHC1G04 but distinguishes itself through integrated Schmitt-trigger inputs. The DCKJ designation indicates a specific packaging variant within the broader AHC family portfolio.
