74AHCT30D,112

Overview

The Nexperia 74AHCT30D,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. It is housed in a SO14 plastic small outline package (SOT108-1) featuring a body width of 3.9 mm. The component supports an ambient operating temperature range 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 actions for improved noise immunity.
• Inputs accept voltages higher than the supply voltage (VCC).
• Compatible with Low-power Schottky TTL (LSTTL) pinout.

Applications

• Digital signal processing circuits requiring multi-input logic operations.
• Interface modules connecting TTL-level sources to CMOS logic systems.
• General-purpose logic control applications in industrial environments.

Selection Notes

Select this component when an 8-input NAND function is required with TTL-compatible input thresholds. Ensure the design accommodates the 4.5 V to 5.5 V supply voltage range. Confirm that the SO14 package dimensions fit the PCB layout constraints. Verify thermal management requirements against the specified power dissipation limits for the SO14 package.

Part Context

This part belongs to the 74AHCT30 family of 8-input NAND gates manufactured by Nexperia. It shares functional compatibility with the 74AHC30 variant but differs in input threshold levels, specifically supporting TTL logic levels. The 'D' designation indicates the SO14 package type, while ',112' denotes the standard tape-and-reel or tube packaging configuration defined by the manufacturer.

Replacement Considerations

Direct substitutes include other 74AHCT30 variants in different packages, such as 74AHCT30PW (TSSOP14), 74AHCT30BQ (DHVQFN14), or 74AHCT30BZ (DHXQFN14). Cross-family replacements like 74HC30 are not electrically equivalent due to differing input voltage thresholds.
