74AHCT30PW,112

Overview

The Nexperia 74AHCT30PW,112 is an 8-input NAND gate implemented in high-speed Si-gate CMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL-level input signals. The device provides balanced propagation delays with Schmitt-trigger action on all inputs, ensuring tolerance to slow signal transitions. It features overvoltage-tolerant inputs that accept voltages higher than VCC. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). The component is housed in a TSSOP14 package (SOT402-1) and supports operating temperatures from -40 °C to +125 °C.

Feature Summary

• Implements an 8-input NAND logic function using high-speed Si-gate CMOS technology.
• All inputs feature Schmitt-trigger action for improved noise immunity and tolerance to slow rise/fall times.
• Inputs are overvoltage tolerant, accepting voltages exceeding the supply voltage level.
• Provides robust electrostatic discharge protection compliant with JEDEC standards.

Applications

• Digital logic circuits requiring an 8-input NAND function
• Mixed-voltage environments utilizing TTL-compatible inputs
• Signal processing applications requiring Schmitt-triggered inputs

Procurement Notes

Verify the specific ordering suffix ',112' corresponds to the TSSOP14 package variant when sourcing. Confirm the manufacturer is Nexperia USA Inc. Ensure the component meets RoHS compliance requirements. Check for any recent Product Change Notices regarding marking or assembly updates before finalizing procurement.

Selection Notes

Select this component when an 8-input NAND gate is required with TTL-compatible input levels. It is suitable for designs needing Schmitt-trigger inputs to handle noisy or slow signals. Verify that the 4.5 V to 5.5 V supply voltage range aligns with the system power rails. Consider the TSSOP14 package dimensions if board space is constrained.

Part Context

This part belongs to the 74AHC/AHCT family of high-speed CMOS logic devices. It is pin-compatible with Low-power Schottky TTL (LSTTL) standards. The 'AHCT' designation indicates compatibility with TTL logic levels while maintaining CMOS performance characteristics. It shares functional similarities with other 74-series logic gates but offers enhanced speed and lower power consumption.

Replacement Considerations

The 74HC30PW,112 is a similar device but uses CMOS input levels rather than TTL levels. Ensure input voltage compatibility when substituting. Other packages such as SO14 (74AHCT30D) offer the same functionality in different form factors.
