74HCT30DB,118

Overview

The Nexperia 74HCT30DB,118 is an 8-input NAND gate belonging to the HCT logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports ambient temperatures from -40 °C to +125 °C. The device features TTL-compatible input levels and CMOS low power dissipation. It utilizes a 14-lead SSOP plastic small outline package (SOT337-1). Static characteristics include high noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B.

Feature Summary

• Provides single-gate 8-input NAND functionality with clamp diodes on inputs for voltage interfacing.
• Ensures high noise immunity and robust ESD protection meeting ANSI/ESDA/JEDEC standards.
• Delivers CMOS low power dissipation while maintaining compatibility with standard TTL logic levels.

Applications

• Digital logic circuit design requiring multi-input NAND operations
• Signal processing systems utilizing TTL-to-CMOS interface requirements
• Industrial control applications operating across extended temperature ranges

Procurement Notes

Verify component authenticity through authorized Nexperia distributors or verified supply chain channels. Confirm that the specific ordering suffix matches the required SSOP package variant. Ensure compliance with RoHS directives and JEDEC standards relevant to the target application environment before finalizing procurement orders.

Selection Notes

Select this component when an 8-input NAND function is necessary within a system constrained by the HCT voltage specifications. The wide operating temperature range makes it suitable for demanding industrial environments. Verify that the SSOP footprint aligns with existing PCB layout constraints and that the TTL input thresholds match the driving source logic levels.

Part Context

This part belongs to the 74HCT30 family of 8-input NAND gates manufactured by Nexperia. It represents the HCT variant specifically optimized for operation at 5 V nominal supply voltages. The DB suffix indicates the specific SSOP-14 package configuration, distinguishing it from other physical form factors available within the broader 74HC/HCT product line.

Replacement Considerations

The official datasheet revision history explicitly states that the type number 74HCT30DB has been removed from current production lists. Designers must consult the manufacturer's latest documentation for valid substitute part numbers or alternative package options compatible with the same logical function.
