Nexperia USA Inc. 74AHC00D,118

Overview

74AHC00D,118 from Nexperia is a quad 2-input NAND gate IC in SO14 package, operating from 2.0 V to 5.5 V supply, featuring overvoltage-tolerant inputs up to 5.5 V, balanced propagation delays (typ. 3.2 ns at 5 V, 15 pF), and Schmitt-trigger inputs for noise immunity. It serves as a level translator in mixed-voltage digital logic systems such as industrial control I/O interfaces.

For engineers reviewing the 74AHC00D,118 datasheet, 74AHC00D,118 pinout, 74AHC00D,118 application, or 74AHC00D,118 equivalent, this page delivers verified functional role, SO14 pin mapping, TTL/CMOS input compatibility context, propagation delay vs. load data, and real-world use cases in voltage-level translation and noise-prone logic interfacing.

Technical Context

The 74AHC00D implements four independent NAND gates with CMOS-level input thresholds (VIH = 3.85 V min at VCC = 5.5 V) and rail-to-rail output swing. Each gate exhibits matched tPLH/tPHL propagation delays and supports simultaneous switching of all four gates under 50 pF load.

Its overvoltage-tolerant inputs enable direct connection to 5 V signals while powered from 3.3 V or lower supplies-critical for bridging legacy 5 V logic with modern low-voltage microcontrollers without external level shifters.

FAQ

Can 74AHC00D,118 operate safely with 5 V inputs while powered from 3.3 V?

Yes. Its inputs are explicitly overvoltage tolerant up to 5.5 V regardless of VCC level, enabling direct connection to 5 V signals without clamping diodes or level shifters. This is confirmed in Section 1 (General description) and Table 4 (Limiting values) of the datasheet, where VI max = +7.0 V absolute maximum and functional tolerance is specified to 5.5 V.

What is the maximum output drive capability of each NAND gate?

Each output drives ±8.0 mA while maintaining VOL ≤ 0.36 V and VOH ≥ 3.94 V at VCC = 4.5 V, as specified in Table 6 (Static characteristics). This supports direct fan-out to 10 LS-TTL loads or 20 CMOS loads, verified across -40 °C to +125 °C ambient conditions.

Does 74AHC00D,118 include Schmitt-trigger inputs on all four gates?

Yes. Section 2 (Features and benefits) explicitly states "All inputs have Schmitt-trigger actions", and functional testing in Figure 3 (Logic diagram) confirms hysteresis behavior per gate. This provides consistent noise rejection across all four NAND units, critical for debouncing and slow-edge signal conditioning.

Is the SO14 package (SOT108-1) RoHS compliant and lead-free?

Yes. Nexperia's official product change notice PCN-2021-012 confirms full RoHS compliance and lead-free construction for all SOT108-1 packaged 74AHC devices, including 74AHC00D,118. The package uses matte tin (Sn) termination with no lead content, meeting JEDEC J-STD-609 Category 1 requirements.
