74HCT3G07DC-Q100H

Overview

The Nexperia 74HCT3G07DC-Q100H is a triple buffer with open-drain outputs, part of the AEC-Q100 Grade 1 qualified 74HCT series. 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, CMOS low power dissipation, and high noise immunity. It includes clamp diodes on inputs for interfacing with voltages exceeding VCC. The component is housed in an SOT765-1 (VSSOP8) package.

Feature Summary

• Automotive product qualification in accordance with AEC-Q100 (Grade 1)
• Wide supply voltage range from 2.0 V to 6.0 V
• High noise immunity and latch-up performance exceeds 100 mA per JESD 78 Class II Level B
• ESD protection: HBM exceeds 2000 V and CDM exceeds 1000 V

Applications

• Automotive applications
• Mixed voltage level conversion between 5 V and 3.3 V systems
• Open-drain output driving for bus lines or LED indicators

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the DC suffix denotes the VSSOP8 form factor. Confirm that the H suffix aligns with your preferred reel or cut tape packaging requirements. Ensure the design accounts for the specified operating temperature range and supply voltage constraints defined in the datasheet.

Selection Notes

Select this component when automotive-grade reliability is required alongside TTL-compatible logic levels. The open-drain output configuration allows for wired-AND connections and operation at varying voltage levels compared to the standard push-pull outputs found in other logic families. Consider the VSSOP8 package dimensions for PCB layout constraints.

Part Context

This device belongs to the 74HCT3G07-Q100 family of triple buffers with open-drain outputs. It is designed for automotive environments requiring robust ESD protection and wide temperature operation. The HCT logic family ensures compatibility with standard TTL inputs while maintaining CMOS power efficiency.

Replacement Considerations

Direct replacements include the 74HC3G07DC-Q100H, though it requires CMOS input levels rather than TTL. Other compatible parts within the same family are the 74HCT3G07DP-Q100H (TSSOP8 package). Verify pinout and electrical characteristics before substitution.
