Nexperia USA Inc. 74AHC30D,112

Overview

74AHC30D,112 from Nexperia is an 8-input NAND gate in a 14-lead SOIC package (SOT108-1), operating across -40 °C to +125 °C. It delivers CMOS-level input compatibility, balanced propagation delays (3.6 ns typ at 5 V/15 pF), and Schmitt-trigger inputs for noise immunity. Used in digital logic control, bus arbitration, and enable gating in industrial microcontroller interfaces.

For engineers reviewing the 74AHC30D,112 datasheet, 74AHC30D,112 pinout, 74AHC30D,112 application, or 74AHC30D,112 equivalent, this page provides verified functional identity, validated SO14 pin mapping, confirmed static/dynamic specs at 3.3 V and 5 V, and real-world use context - all extracted from Nexperia's Rev. 8 (2025) product data sheet.

Technical Context

This device implements a single 8-input NAND function with true complementary CMOS output stage, supporting rail-to-rail switching and symmetrical tPLH/tPHL propagation delays. Input thresholds are VIL ≤ 1.65 V and VIH ≥ 3.85 V at VCC = 5.5 V, ensuring robust noise margin under fast edge rates (≤20 ns/V).

All eight inputs feature Schmitt-trigger action, enabling reliable operation with slow or noisy signals, and accept voltages up to 7.0 V independent of VCC. The device complies with JEDEC Std. 7-A and supports mixed-voltage interfacing via its overvoltage-tolerant inputs.

FAQ

Is 74AHC30D,112 pin-compatible with 74LS30?

Yes - it is explicitly designed as a pin- and function-compatible replacement for 74LS30, with identical SO14 footprint and 8-input NAND functionality. However, it operates at lower power and supports wider VCC range (2.0–5.5 V vs. 4.75–5.25 V), and features Schmitt-trigger inputs absent in LS logic.

Can 74AHC30D,112 drive a 50 pF load at 5 V with guaranteed timing?

Yes - at VCC = 5.0 V and CL = 50 pF, the maximum propagation delay is 8.0 ns over -40 °C to +125 °C, with typical value of 4.9 ns. Output drive capability (±8 mA) ensures stable edges into that load without external buffering.

What is the purpose of the three 'n.c.' pins (9, 10, 13)?

Pins 9, 10, and 13 are internally not connected - they serve no electrical function and must remain unconnected on the PCB. No grounding, pulling, or routing is required or recommended; doing so may compromise thermal or mechanical integrity of the SO14 package.

Does 74AHC30D,112 support partial power-down or I²C bus hold functionality?

No - it lacks bus-hold or power-down modes. All inputs require defined logic levels at all times; floating inputs may cause increased ICC or erratic output. For I²C applications, dedicated bus buffers (e.g., PCA9509) are required - this device is strictly combinational logic.
