74HCT2G14GV-Q100H

Overview

The Nexperia 74HCT2G14GV-Q100H is a dual inverting Schmitt trigger integrated circuit belonging to the 74HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL input levels, balanced propagation delays, and unlimited input rise and fall times. It includes clamp diodes on inputs for interfacing with voltages exceeding VCC. The component is qualified to AEC-Q100 Grade 1 standards and housed in a SC-74 (TSOP6) package.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Schmitt trigger inputs transform slowly changing signals into sharply defined jitter-free outputs
• High noise immunity and CMOS low power dissipation
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B

Applications

• Wave and pulse shaper for highly noisy environments
• Astable multivibrators
• Monostable multivibrators

Procurement Notes

Verify that the specific suffix GV corresponds to the SC-74 (TSOP6) package variant when sourcing. Confirm the HCT logic level requirement matches the system's TTL interface needs rather than standard HC CMOS levels. Ensure the design accounts for the specified operating temperature range up to +125 °C if deployed in automotive or industrial environments.

Selection Notes

Select this component when dual inverting functions with Schmitt trigger hysteresis are required in space-constrained designs. The SC-74 package offers a compact surface-mount solution suitable for high-density PCB layouts. The HCT series ensures compatibility with standard TTL logic levels while maintaining CMOS power efficiency characteristics.

Part Context

This part is part of the Nexperia 74HCT2G14-Q100 series, which also includes the 74HC2G14-Q100 variant. While both share the same physical package and pinout, the HCT version is specifically optimized for TTL input levels, whereas the HC version supports broader CMOS input levels across a wider voltage range. Both are designed for automotive applications under the Q100 qualification.

Replacement Considerations

The 74HC2G14GV-Q100H serves as a functional alternative but requires verification of input voltage compatibility due to its CMOS level specifications instead of TTL.
