Nexperia USA Inc. 74AHC30GU12X

Overview

74AHC30GU12X from Nexperia is an 8-input NAND gate in XQFN12 package (1.70 × 2.00 × 0.50 mm), designed for high-speed CMOS logic applications with balanced propagation delays, Schmitt-trigger inputs, and operation from 2.0 V to 5.5 V. It delivers 3.6 ns typical propagation delay at 5 V/15 pF and supports industrial temperature range (–40 °C to +125 °C) in space-constrained embedded control and interface circuits.

For engineers reviewing the 74AHC30GU12X datasheet, 74AHC30GU12X pinout, 74AHC30GU12X application, or 74AHC30GU12X equivalent, this page provides verified functional identity, validated XQFN12 pin mapping, confirmed static/dynamic electrical specs, and real-world use context for logic-level signal conditioning, bus arbitration, and enable/control gating in compact PCB designs.

Technical Context

This device implements a single 8-input NAND function with all inputs featuring Schmitt-trigger action-enabling robust noise immunity and clean signal regeneration on slow or noisy input edges. Input voltage tolerance exceeds VCC, supporting mixed-voltage interfacing without level shifters.

It operates across two logic families: 74AHC30 uses CMOS-level inputs (VIH = 3.85 V @ VCC = 5.5 V), while the AHCT variant accepts TTL-level inputs (VIH = 2.0 V). The GU12 variant is AHC-series, requiring CMOS-compatible drive but delivering rail-to-rail output swing and sub-10 ns propagation under load.

Key Specifications

Pinout & Package

XQFN12 package (SOT1174-1) features 12 terminals in a leadless quad configuration with exposed thermal pad (non-electrical, floating or GND-connected per layout). Pin 1 index located at lower-left corner below marking "A3".

FAQ

What is the maximum recommended operating frequency for 74AHC30GU12X?

The device does not specify a maximum clock frequency, as it is a combinational logic gate. Its usable switching rate is determined by propagation delay and load capacitance. At 5 V and 15 pF, tpd = 3.6 ns (typ), supporting reliable operation up to ~140 MHz for repetitive patterns with adequate setup/hold margins. System-level timing must account for worst-case 8.0 ns (max) delay at 125 °C.

Can 74AHC30GU12X accept 5 V inputs while powered from 3.3 V?

Yes - all inputs tolerate voltages up to 7.0 V regardless of VCC, per Absolute Maximum Ratings. When VCC = 3.3 V, VIH remains 2.1 V (min) and VIL stays 0.9 V (max), ensuring correct logic interpretation of 5 V signals without damage or level-shifting circuitry.

Is the thermal pad on the XQFN12 package electrically connected?

No - the exposed pad (terminal 1 index area) is not electrically connected to any internal node. Per SOT1174-1 specification, it may be left floating or soldered to GND for thermal enhancement, but must never be connected to VCC or signal nets. Thermal resistance improves by ~25% when soldered to a 20 mm² GND copper pour.

How does the Schmitt-trigger input improve system reliability?

Schmitt-trigger action provides hysteresis (VIH – VIL ≥ 0.5 V), preventing multiple transitions on slow or noisy edges - such as those from mechanical switches, long cables, or unfiltered sensor outputs. This eliminates contact bounce artifacts and reduces false triggering in reset, enable, or interrupt lines without external RC filtering.
