74HCT2G32DC-Q100H

Overview

The Nexperia 74HCT2G32DC-Q100H is a dual 2-input OR gate qualified to AEC-Q100 Grade 1 standards for automotive applications. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input levels. The device is housed in an SOT765-1 (VSSOP8) package with eight leads. Static characteristics specify low power dissipation and high noise immunity, while dynamic performance includes a typical propagation delay of 24 ns at 4.5 V. Input clamp diodes allow interfacing to voltages exceeding VCC using current limiting resistors.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications
• TTL input switching levels compatible with standard logic families
• Input clamp diodes enable overvoltage tolerance beyond the supply rail
• High noise immunity and CMOS low power dissipation design

Applications

• Automotive electronic systems requiring robust logic gating
• Mixed voltage environments utilizing current limiting resistor interfaces
• General purpose digital signal processing circuits

Procurement Notes

Verify that the specific ordering suffix matches the required package variant, as the DC designation corresponds to the VSSOP8 form factor. Confirm that the component meets the AEC-Q100 Grade 1 reliability requirements necessary for your target automotive application environment. Ensure input voltage conditions align with the specified TTL level thresholds during system integration testing.

Selection Notes

Select this component when TTL-compatible inputs are required alongside automotive grade reliability standards. The dual configuration provides two independent OR functions within a compact footprint suitable for space-constrained designs. Consider the wide operating temperature range and latch-up performance when designing for harsh environmental conditions or high-noise industrial settings.

Part Context

This part belongs to the Nexperia 74HCT2G32-Q100 family of dual 2-input OR gates. It shares functional similarities with the HC variant but utilizes HCT technology for TTL-level input compatibility. The family supports various package options including TSSOP8 and VSSOP8, all maintaining consistent electrical characteristics and automotive qualification status across different physical form factors.

Replacement Considerations

The 74HC2G32DC-Q100H serves as a direct pin-compatible alternative within the same family, differing only in input logic level specifications from TTL to CMOS.
