74HCT2G00DC-Q100H

Overview

The Nexperia 74HCT2G00DC-Q100H is a dual 2-input NAND gate designed for automotive applications, qualified to AEC-Q100 Grade 1 standards. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels. The device utilizes a VSSOP8 (SOT765-1) package with an operating temperature range from -40 °C to +125 °C. Static characteristics include high-level output voltages up to 4.32 V at 4.5 V supply and low leakage currents. Dynamic performance specifies propagation delays of 29 ns maximum at 4.5 V.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• TTL input switching levels compatible with standard logic families
• High noise immunity with symmetrical output impedance
• Robust ESD protection exceeding 2000 V HBM and 1000 V CDM

Applications

• Automotive electronic systems requiring Grade 1 component qualification
• Digital signal processing circuits utilizing dual NAND logic functions
• Mixed-signal interfaces leveraging clamp diodes for over-voltage tolerance

Procurement Notes

Verify the specific suffix 'Q100H' against official Nexperia documentation to confirm automotive grade status and tape-and-reel packaging configuration. Ensure compatibility with VSSOP8 footprint dimensions during PCB layout. Confirm that the TTL input threshold requirements align with the system's logic voltage levels before finalizing procurement specifications.

Selection Notes

Select this component when automotive reliability under AEC-Q100 Grade 1 is mandatory. Choose this part over HC variants if TTL-compatible input thresholds are required for interfacing with legacy logic. Consider the VSSOP8 package constraints regarding thermal dissipation and board space. Validate that the 4.5 V to 5.5 V supply range matches the target application power rails.

Part Context

This device belongs to the Nexperia 74HCT2G00-Q100 family of dual 2-input NAND gates. It shares functional similarities with the 74HC2G00-Q100 but differs in input threshold specifications. The DC suffix denotes the VSSOP8 package variant, distinct from the DP TSSOP8 version. All members of this series adhere to strict automotive quality and reliability protocols.

Replacement Considerations

The 74HC2G00DC-Q100H serves as a pin-compatible alternative within the same family, differing only in input logic level specifications.
