74HC14DR2G

Overview

The onsemi 74HC14DR2G is a Hex Schmitt-Trigger Inverter fabricated with high-performance silicon-gate CMOS technology. It features six independent inverters in a 14-pin SOIC package. The device operates within a supply voltage range of 2.0 V to 6.0 V and supports an operating temperature from -55°C to +125°C. It provides an output drive capability of 10 LSTTL loads, ensuring compatibility with standard logic families. Key electrical characteristics include low input current (1.0 µA max) and high noise immunity typical of CMOS devices.

Feature Summary

• Schmitt-trigger inputs provide hysteresis to square up slow rise and fall times
• Outputs directly interface to CMOS, NMOS, and TTL logic families
• High noise immunity characteristic of CMOS devices
• Pb-free packaging compliant with environmental standards

Applications

• Squaring up slow input signals in noisy environments
• Interface between different logic families such as CMOS and TTL
• Signal conditioning for digital circuits requiring noise rejection

Procurement Notes

Verify the specific ordering suffix 'DR2G' corresponds to the SOIC-14 package and tape & reel shipping configuration. Confirm RoHS compliance status and check for any recent product change notices that may affect pinout or electrical specifications before finalizing procurement.

Selection Notes

Select this component when hex inverter functionality with Schmitt trigger inputs is required. Ensure the application voltage falls within the 2.0 V to 6.0 V range. Consider the -55°C to +125°C temperature range for industrial or automotive environments. Verify that the 14-pin SOIC package fits the PCB layout constraints.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices. It shares pinout compatibility with LS14, LS04, and HC04 variants. The device is designed for applications requiring low power dissipation while maintaining speed comparable to bipolar Schottky TTL. It is manufactured by onsemi under the Semiconductor Components Industries, LLC brand.

Replacement Considerations

Direct substitutes include other manufacturers' 74HC14 parts in SOIC-14 packages. Ensure replacement parts maintain the same Schmitt trigger input characteristics and operate within the specified voltage and temperature ranges. Verify package dimensions and pin assignments match exactly.
