Nexperia USA Inc. 74AHC30D,118

Overview

74AHC30D,118 from Nexperia is an 8-input NAND gate in a 14-lead SOIC package (SOT108-1), operating from 2.0 V to 5.5 V with CMOS-level inputs, 8 ns max propagation delay at 5 V/50 pF, and guaranteed operation from –40 °C to +125 °C. It serves as a high-speed logic combiner in industrial control signal conditioning, FPGA I/O expansion, and power-on reset sequencing.

For engineers reviewing the 74AHC30D,118 datasheet, 74AHC30D,118 pinout, 74AHC30D,118 application, or 74AHC30D,118 equivalent, this device delivers deterministic 8-input logic evaluation with Schmitt-trigger input hysteresis, rail-to-rail output swing, and robust ESD protection-critical for noise-prone sensor interface and bus arbitration circuits.

Technical Context

The 74AHC30D implements a single 8-input NAND function using high-speed Si-gate CMOS technology compliant with JEDEC Std 7-A and pin-compatible with LSTTL. Its inputs accept voltages up to 7.0 V independent of VCC, enabling mixed-voltage interfacing.

All eight inputs feature Schmitt-trigger action with typical hysteresis of 0.3 V at 3.3 V, ensuring reliable noise rejection in slow-rising or noisy control signals. The output drives ±25 mA and maintains VOL ≤ 0.55 V at 8 mA sink current across the full temperature range.

FAQ

What is the maximum input voltage the 74AHC30D,118 can tolerate?

The 74AHC30D,118 accepts input voltages from –0.5 V to +7.0 V, independent of VCC level. This allows safe interfacing with higher-voltage signals (e.g., 5 V or 7 V sources) even when powered from 3.3 V, eliminating external level shifters in mixed-voltage designs.

Does the 74AHC30D,118 require external pull-up or pull-down resistors on unused inputs?

No. All eight inputs (A–H) must be actively driven to defined logic levels; floating inputs are prohibited due to CMOS gate susceptibility to leakage-induced oscillation and increased ICC. Unused inputs should be tied to VCC or GND - never left open.

Can the 74AHC30D,118 drive a 50 pF load at 10 MHz while staying within power limits?

Yes. At VCC = 5 V, f_i = 10 MHz, and 8 inputs switching, dynamic power is PD ≈ CPD × VCC² × f_i × N = 10 pF × 25 V² × 10 MHz × 8 = 20 mW - well below the SO14 package's 500 mW P_tot limit at +25 °C.

Is the 74AHC30D,118 suitable for automotive applications?

No. While rated for –40 °C to +125 °C, the 74AHC30D,118 is not AEC-Q100 qualified. Nexperia offers the 74AHC30-Q100 variant (same functionality, automotive-qualified) for under-hood or safety-critical vehicle systems.
