Overview
The 74AHCT30BQ,115 is an 8-input NAND gate from the Nexperia AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels. The device provides balanced propagation delays with Schmitt-trigger action on all inputs, allowing them to accept voltages higher than VCC. It includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). The component is housed in a DHVQFN14 package (SOT762-1) and supports operating temperatures from -40 °C to +125 °C.
Feature Summary
- Implements an 8-input NAND logic function with balanced propagation delays.
- All inputs feature Schmitt-trigger action for improved noise immunity.
- Inputs are overvoltage tolerant, accepting voltages higher than the supply voltage.
- Provides robust electrostatic discharge protection compliant with JEDEC standards.
Applications
- Digital signal processing circuits requiring multi-input logic operations
- Mixed voltage environments utilizing TTL-compatible interfaces
- Industrial control systems operating across extended temperature ranges

Selection Notes
Select this component when an 8-input NAND function is required with TTL-level compatibility. The AHCT series ensures compatibility with standard TTL outputs while maintaining CMOS performance characteristics. Ensure the design accommodates the DHVQFN14 package dimensions and thermal requirements for the intended application environment.
Part Context
This part belongs to the 74AHC/AHCT30 family of high-speed Si-gate CMOS devices. These components are pin-compatible with Low-power Schottky TTL (LSTTL) and comply with JEDEC standard No. 7-A. The family offers multiple package options including SO14, TSSOP14, DHVQFN14, and DHXQFN14, providing flexibility for various PCB layout constraints.
Replacement Considerations
Direct replacements include other packages of the same logic type such as 74AHCT30D (SO14), 74AHCT30PW (TSSOP14), or 74AHCT30BZ (DHXQFN14). Verify that the substitute package maintains the required thermal dissipation capabilities and physical footprint constraints.
