SN74AHC1G14DCKRG4

Overview

The SN74AHC1G14DCKRG4 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 features over-voltage tolerant inputs. The device utilizes a push-pull output configuration with balanced drive capabilities, supporting maximum currents of 8mA for both high and low states. It is housed in a compact SC-70-5 (SOT-353) surface-mount package. The component is rated for an operating temperature range of -40°C to +125°C and includes built-in Schmitt-trigger functionality to ensure clean signal transitions.

Feature Summary

• Schmitt-trigger input action provides defined thresholds to eliminate noise-induced false triggering on slow-rising signals
• Over-voltage tolerant inputs allow safe operation when interfacing with higher voltage logic levels without external protection
• Balanced push-pull outputs deliver symmetrical drive strength for consistent signal integrity across load conditions

Applications

• Signal conditioning for noisy digital lines requiring noise immunity
• Waveform shaping of slow or distorted input signals
• Interface circuits between different voltage domains

Procurement Notes

Verify the specific ordering suffix RG4 against the manufacturer's current datasheet to confirm packaging details and tape-and-reel specifications. Ensure the component version matches the required RoHS compliance standards for your assembly process. Cross-reference the SC-70-5 footprint dimensions with your PCB design library to guarantee mechanical compatibility during placement.

Selection Notes

Select this component when Schmitt-trigger hysteresis is required to stabilize signals with significant noise or slow edge rates. The AHC series offers a balance of speed and power consumption suitable for general-purpose logic applications. Consider the SC-70-5 package size constraints and verify that the 2V to 5.5V supply range aligns with your system's power architecture.

Part Context

This part belongs to the SN74AHC1Gxx series of single-gate logic devices designed for space-constrained designs. The AHC technology combines advanced CMOS processes to achieve high-speed performance while maintaining low static power dissipation. The DCK variant specifically denotes the SC-70-5 plastic small outline package, which is widely used in portable and high-density electronic equipment.
