74AHC1G14SE-7

Overview

The 74AHC1G14SE-7 is a single-input Schmitt-trigger inverter from Diodes Incorporated, part of the AHC logic family. It operates within a supply voltage range of 2.0V to 5.5V and features standard push-pull outputs capable of ±8mA drive at 5.0V. The device utilizes SOT353 packaging and supports an operating temperature range of -40°C to +125°C. Propagation delay varies between 0.6ns and 20.5ns depending on load capacitance and voltage conditions.

Feature Summary

• Schmitt trigger action at all inputs provides tolerance for slower input rise and fall times.
• ESD protection exceeds 200V Machine Model, 2000V Human Body Model, and 1000V Charged Device Model standards.
• Latch-up performance exceeds 100mA per JESD 78 Class II specifications.

Applications

• General purpose logic circuits
• PCs, networking equipment, notebooks, and netbooks
• Computer peripherals including hard drives and CD/DVD ROMs
• TV, DVD, DVR, and set-top boxes

Procurement Notes

Verify the specific package suffix 'SE' corresponds to the SOT353 form factor required for your design. Confirm that the RoHS compliance status meets your regional regulatory requirements. Ensure the tape and reel quantity aligns with your production volume needs. Validate that the operating temperature range satisfies your environmental constraints.

Selection Notes

Select this component when signal integrity requires noise immunity against slow-rising waveforms due to its Schmitt trigger inputs. Consider the low power consumption characteristics suitable for battery-operated devices. Evaluate the compact SOT353 footprint if space-constrained PCB layouts are necessary. Verify compatibility with the target system's voltage levels across the full 2.0V to 5.5V range.
