74HCT30D,652

Overview

The Nexperia 74HCT30D,652 is an 8-input NAND gate in the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL-compatible input levels. The device provides low power dissipation and high noise immunity. It includes input clamp diodes for interfacing with voltages exceeding VCC. The component supports ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). It is housed in a 14-lead SOIC package (SOT108-1) and functions reliably across an ambient temperature range of -40 °C to +125 °C.

Feature Summary

• CMOS technology ensures low power dissipation while maintaining high noise immunity.
• TTL-compatible input levels allow direct interfacing with standard digital logic systems.
• Input clamp diodes enable safe operation when interfacing with voltages higher than the supply voltage.
• Robust ESD protection meets JEDEC standards for both Human Body Model and Charged Device Model.

Applications

• General-purpose digital logic processing
• Signal gating and control circuits
• Interface between TTL and CMOS logic domains

Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and tape/reel specifications. Confirm that the component status remains active or qualified for new designs, as manufacturing updates may occur. Ensure compliance with RoHS directives and check for any recent product change notices affecting marking or assembly sources before finalizing procurement plans.

Selection Notes

Select this component when an 8-input NAND function is required with TTL-compatible inputs. The HCT series is appropriate for systems operating at 5 V where compatibility with older TTL devices is necessary. Consider the SOIC package dimensions for PCB layout constraints. Verify that the propagation delay characteristics meet the timing requirements of the target application circuit.

Part Context

This part belongs to the 74HCT30 family of 8-input NAND gates manufactured by Nexperia. It shares functional similarities with other members of the 74HCT series but is distinct from the 74HC30 variant which utilizes CMOS input levels. The 'D' designation indicates the SOIC plastic small outline package, while the ',652' suffix typically denotes specific packaging and handling configurations defined by the manufacturer.

Replacement Considerations

Direct replacements include the 74HCT30D,653 variant which shares identical electrical characteristics and pinout. Other compatible options within the same logic family should be verified against the official datasheet to ensure matching input/output voltage levels and package dimensions.
