74HC30DB,112

Overview

The NXP USA Inc. 74HC30DB,112 is an obsolete 8-input NAND gate from the 74HC logic family. It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS low power dissipation, high noise immunity, and ESD protection exceeding 2000 V (HBM). Inputs include clamp diodes for interfacing with voltages exceeding VCC. The component was manufactured in a 14-lead SSOP package (SOT337-1) but has been removed from current product specifications.

Feature Summary

• Provides a single 8-input NAND logic function
• Features inputs with integrated clamp diodes
• Offers high noise immunity and low power consumption
• Includes robust electrostatic discharge protection

Applications

• Digital logic circuit design
• Signal processing systems
• General-purpose electronic equipment

Procurement Notes

This specific part number is obsolete and no longer manufactured by Nexperia. Verify availability through authorized distributors or secondary markets. Confirm that the legacy SSOP-14 package meets your board layout requirements. Ensure that any replacement components maintain compatibility with your existing system voltage levels and interface standards.

Selection Notes

Select this component only if the legacy 14-lead SSOP form factor is strictly required for a specific application. Evaluate alternative packages such as SO14 or TSSOP14 if physical constraints allow. Consider the operational limits of the 74HC series when designing for varying supply voltages and temperature ranges.

Part Context

The 74HC30DB,112 belongs to the 74HC series of high-speed CMOS logic devices. This series is designed for general-purpose digital applications requiring low power and wide voltage operation. The 'DB' suffix indicates the specific SSOP-14 packaging variant, which has since been discontinued in favor of other package options like SO14 and TSSOP14.

Replacement Considerations

Public confirmed substitute part numbers: 74HC30D, 74HC30PW.
