Nexperia USA Inc. 74HC03PW,118

Overview

74HC03PW,118 from Nexperia is a quad 2-input NAND gate IC with open-drain outputs, designed for wired-AND logic, level translation, and bus interface applications. It operates from 2.0 V to 6.0 V, delivers propagation delay as low as 8 ns at VCC = 6.0 V, supports -40 °C to +125 °C ambient range, and features CMOS-level inputs with input clamp diodes enabling overvoltage-tolerant interfacing.

For engineers reviewing the 74HC03PW,118 datasheet, 74HC03PW,118 pinout, 74HC03PW,118 application, or 74HC03PW,118 equivalent, this device is selected for robust digital logic interfacing where open-drain flexibility, wide supply tolerance, and high noise immunity are required in industrial control, sensor signal conditioning, and I²C-compatible bus systems.

Technical Context

The 74HC03PW,118 implements four independent 2-input NAND gates, each with an open-drain output stage that requires external pull-up for HIGH-level assertion. Its input structure includes integrated clamp diodes, allowing safe connection to signals exceeding VCC when used with current-limiting resistors.

It adheres to JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, supports static drive capability up to 5.2 mA at VO = 0.4 V (VCC = 6.0 V), and exhibits input leakage below ±1 μA across temperature - enabling reliable operation in mixed-voltage digital subsystems.

FAQ

Can 74HC03PW,118 be used with 3.3 V and 5 V logic simultaneously?

Yes - its 2.0–6.0 V supply range and input clamp diodes allow safe interfacing between 3.3 V controllers and 5 V peripherals when current-limiting resistors are used on inputs exceeding VCC. The open-drain outputs support pull-up to either voltage rail, enabling true bidirectional level translation without additional components.

What is the maximum sink current per output, and how does it affect pull-up design?

The 74HC03PW,118 guarantees 5.2 mA sink current at VOL ≤ 0.4 V with VCC = 6.0 V. For a 5 V pull-up, a 4.7 kΩ resistor yields ~1 mA load - well within spec and ensuring clean LOW transitions. At 3.3 V, a 2.2 kΩ resistor provides ~1.5 mA, maintaining noise margin while supporting faster rise times on capacitive buses like I²C.

Does this device require external pull-up resistors on all outputs?

Yes - all four outputs are open-drain and cannot source current. External pull-up resistors are mandatory to establish HIGH logic levels. Values between 1 kΩ and 10 kΩ are typical; lower values improve rise time but increase power consumption when outputs are LOW, while higher values reduce power but slow transitions on loaded buses.

How does the −40 °C to +125 °C rating impact reliability in industrial deployments?

This extended temperature grade ensures parametric compliance - including propagation delay, VOL, and VIH/VIL - across the full range without derating. Combined with JESD78 latch-up immunity (>100 mA) and >2000 V HBM ESD protection, it sustains operation in uncontrolled environments such as factory-floor PLCs, motor drives, and outdoor sensor housings without thermal throttling or parameter drift.
