74HCT20D-Q100,118

Overview

The Nexperia 74HCT20D-Q100,118 is a dual 4-input NAND gate housed in an SO14 (SOT108-1) plastic package. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS input levels with TTL-compatible thresholds for the HCT variant. Static characteristics include high-level output voltages up to 5.9 V at 2.0 V supply and low-level output voltages as low as 0.1 V. Dynamic performance specifies propagation delays ranging from 15 ns to 90 ns depending on voltage and temperature conditions.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• Wide operating temperature range extending to +125 °C
• High noise immunity and robust latch-up performance exceeding 100 mA

Applications

• Automotive electronic systems requiring qualified logic components
• Industrial control circuits operating under harsh environmental conditions
• General-purpose digital logic processing in consumer electronics

Procurement Notes

Verify the specific ordering suffix matches the required package type and tape/reel configuration. Confirm that the component version aligns with the latest product data sheet revision to ensure accurate electrical specifications. Check for any recent manufacturing site changes or label updates documented in product change notices before finalizing procurement orders.

Selection Notes

Select this component when automotive reliability and extended temperature operation are mandatory requirements. The HCT logic family ensures compatibility with standard TTL interfaces while maintaining CMOS power efficiency. Ensure the application design accounts for the specified input clamp diodes if interfacing with voltages exceeding the supply rail.

Part Context

This part belongs to the Nexperia 74HCT20-Q100 series of dual 4-input NAND gates. It is designed as a high-speed Si-gate CMOS device compatible with Low-power Schottky TTL (LSTTL). The series includes variants such as the 74HC20D-Q100 and 74HC20PW-Q100, offering different package options like TSSOP14 for diverse PCB layout needs.

Replacement Considerations

The 74HC20D-Q100 serves as a direct functional substitute within the same package. Other members of the 74HCT20-Q100 family may be considered if pin compatibility and logical function remain consistent with the system design requirements.
