74AHCT30D,118

Overview

The Nexperia 74AHCT30D,118 is an 8-input NAND gate housed in a SO14 (SOT108-1) plastic small outline package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features balanced propagation delays with typical values of 6.5 ns at 15 pF load and 8.5 ns at 50 pF load when operating at 5.0 V. It provides high-level output current up to -8.0 mA and low-level output current up to 8.0 mA.

Feature Summary

• Provides a single 8-input NAND logic function
• Accepts input voltages higher than the supply voltage (VCC)
• Includes Schmitt-trigger action on all inputs for noise immunity
• Offers ESD protection exceeding 2000 V via Human Body Model

Applications

• Digital signal processing circuits requiring multi-input logic gating
• Microcontroller peripheral interface design
• Memory address decoding systems
• Industrial control logic implementation

Procurement Notes

Verify that the specific ordering suffix ',118' corresponds to the standard tape-and-reel packaging format required by automated assembly lines. Confirm that the SO14 package variant matches the footprint specifications of the target printed circuit board layout. Ensure compliance with RoHS directives if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when an 8-input NAND function is required with TTL-compatible input levels. The AHCT series ensures compatibility with standard 5 V logic families while maintaining CMOS power efficiency. Verify that the maximum operating temperature of +125 °C meets the thermal requirements of the intended application environment.

Part Context

This part belongs to the 74AHC/AHCT family of high-speed silicon-gate CMOS devices. It is pin-compatible with Low-power Schottky TTL (LSTTL) standards. The 'D' designation indicates the SO14 surface-mount package, while the 'AHCT' prefix specifies TTL-compatible input thresholds suitable for 5 V operation.

Replacement Considerations

Direct substitutes include other manufacturers' 74AHCT30 variants in SOIC-14 packages. Cross-reference pinouts and electrical characteristics to ensure compatibility with existing circuit designs.
