74HCT02D,652

Overview

The Nexperia 74HCT02D,652 is a quad 2-input NOR gate from the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level inputs. The device features four independent NOR gates with data outputs at pins 1, 4, 10, and 13. Inputs are located at pins 2, 3, 5, 6, 8, 9, 11, and 12. Power is supplied via pin 14 (VCC) and ground at pin 7. Propagation delay is typically 11 ns at 4.5 V with a 50 pF load.

Feature Summary

• Provides four independent 2-input NOR logic functions
• Accepts TTL-compatible input voltage levels
• Includes input clamp diodes for overvoltage protection
• Complies with JEDEC standards for noise immunity and latch-up performance

Applications

• Digital logic circuit design
• Signal processing applications
• General-purpose logic implementation

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and temperature range. Confirm current product status as availability may vary by region. Ensure compliance with RoHS directives and REACH regulations before integration into final designs.

Selection Notes

Select this component when TTL-level interfacing is required with CMOS logic families. The SOIC-14 package offers a compact footprint suitable for surface-mount assembly. Verify that the operating temperature range meets the environmental requirements of the target application.

Part Context

This part belongs to the 74HCT series, which bridges TTL and CMOS technologies. The 'D' suffix indicates the SOIC-14 plastic small outline package. The '652' suffix denotes the standard tube packaging format used by Nexperia for distribution.

Replacement Considerations

Check for direct equivalents such as the 74HC02D variant if CMOS-level inputs are acceptable. Verify pin compatibility and electrical characteristics against alternative manufacturers' offerings.
