74AHCT2G08DP-Q100H

Overview

The Nexperia 74AHCT2G08DP-Q100H is a dual 2-input AND gate in the 74AHCT series, housed in an SOT505-2 (TSSOP8) package. 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 switching levels and overvoltage tolerant inputs up to 5.5 V. Static characteristics include a maximum input leakage current of 2.0 μA at -40 °C to +125 °C and a maximum supply current of 40 μA under specified conditions.

Feature Summary

• Qualified for automotive applications according to AEC-Q100 Grade 1 standards
• Features overvoltage tolerant inputs allowing use as translators in mixed voltage environments
• Provides symmetrical output impedance and balanced propagation delays
• Includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM)

Applications

• Automotive electronic systems requiring Grade 1 qualification
• Mixed voltage logic translation between TTL and CMOS domains
• High noise immunity digital signal processing

Procurement Notes

Verify that the specific ordering suffix matches the required TSSOP8 package configuration. Confirm the AHCT designation aligns with system TTL input requirements rather than standard HC CMOS levels. Ensure the component meets the necessary AEC-Q100 Grade 1 automotive qualification standards for the intended deployment environment.

Selection Notes

Select this component when TTL-compatible inputs are required alongside high-speed performance and extended temperature capabilities. The AHCT series ensures compatibility with legacy TTL logic families while offering improved speed over standard variants. Verify that the 4.5 V to 5.5 V operating voltage range matches the target power supply rails.

Part Context

This part belongs to the Nexperia 74AHC_AHCT2G08_Q100 family of dual 2-input AND gates. It shares functional similarities with the 74AHC2G08 variant but utilizes TTL input thresholds. The Q100 suffix indicates automotive-grade reliability and qualification, distinguishing it from standard commercial grade devices within the broader 74-series logic portfolio.

Replacement Considerations

The 74AHC2G08DP-Q100H serves as a pin-compatible alternative if CMOS input levels are acceptable instead of TTL. Other packages such as VSSOP8 (DC suffix) offer physical alternatives within the same electrical specification family.
