74VHCT02BQ,115

Inverter Gates Overview

The Nexperia 74VHCT02BQ,115 is a high-speed Si-gate CMOS quad 2-input NOR gate compliant with JEDEC standard No. 7-A. 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 balanced propagation delays, Schmitt-trigger action on all inputs, and ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Packaged in DHVQFN14 (SOT762-1), it provides four independent NOR logic functions.

Inverter Gates Feature Summary

• Operates with TTL input levels for compatibility with Low-power Schottky TTL (LSTTL)
• All inputs feature Schmitt-trigger action
• Inputs accept voltages higher than the supply voltage (VCC)
• Provides robust electrostatic discharge protection

Inverter Gates Applications

• Logic level translation between LSTTL and CMOS systems
• Digital signal processing circuits requiring NOR logic
• Industrial control systems operating at elevated temperatures

Inverter Gates Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature rating. Confirm compliance with RoHS directives and check for any recent Product Change Notifications (PCN) regarding manufacturing site or material updates. Ensure the component meets the specified JEDEC standards for your application environment.

Inverter Gates Selection Notes

Select this component when TTL-compatible input thresholds are required alongside CMOS output drive capabilities. The DHVQFN14 package offers a compact footprint suitable for space-constrained designs. Verify that the operating voltage remains within the 4.5 V to 5.5 V range to ensure proper functionality and adherence to static and dynamic specifications.

Inverter Gates Part Context

This part belongs to the 74VHC/VHCT series of high-speed silicon-gate CMOS logic devices. The VHCT variant specifically ensures pin compatibility with LSTTL while maintaining CMOS performance characteristics. The BQ suffix indicates the DHVQFN14 package configuration, distinguishing it from SO or TSSOP variants within the same logical family.

Inverter Gates Replacement Considerations

Direct pin-compatible substitutes include other manufacturers' 74VHCT02 devices meeting JEDEC standard 7-A. For equivalent performance in different packages, consider Nexperia 74VHCT02D (SO14) or 74VHCT02PW (TSSOP14). Verify input/output electrical characteristics match before substitution.

Inverter Gates FAQ
