Nexperia USA Inc. 74HC05PW,118

Overview

74HC05PW,118 from Nexperia is a hex inverter IC with six independent open-drain outputs, designed for level-shifting, wired-OR logic, and bus interface applications. It operates from 2.0 V to 6.0 V, supports -40 °C to +125 °C ambient range, delivers 5.2 mA sink current at VCC = 6.0 V, and exhibits 10 ns typical tPLZ propagation delay at 4.5 V supply.

For engineers reviewing the 74HC05PW,118 datasheet, 74HC05PW,118 pinout, 74HC05PW,118 application, or 74HC05PW,118 equivalent, this device is selected for open-drain logic interfacing where active-LOW wired-OR functionality, CMOS input compatibility, and thermal robustness across industrial temperature ranges are required.

Technical Context

The 74HC05PW implements six identical inverting gates, each with an open-drain output stage requiring external pull-up resistors to define HIGH-level logic states. Its functional behavior follows standard TTL/CMOS inversion logic: LOW input yields high-impedance (Z) output; HIGH input yields LOW output.

It uses standard HC-series silicon process technology with ESD protection per JS-001 Class 2 (>2000 V HBM) and JS-002 Class C3 (>1000 V CDM), and complies with JEDEC 7A and JESD78 Class II latch-up immunity (>100 mA). No internal pull-ups or enable controls are present-operation is purely combinational and static.

FAQ

Does the 74HC05PW,118 require external pull-up resistors on all outputs?

Yes-every output (pins 2, 4, 6, 8, 10, 12) is open-drain and cannot source current. A pull-up resistor to VCC or another logic rail is mandatory to establish a defined HIGH logic level. Typical values range from 2.2 kΩ to 10 kΩ depending on bus capacitance and rise-time requirements.

Can the 74HC05PW,118 be used in place of a standard 74HC04 hex inverter?

No-it is not a drop-in replacement. Unlike the 74HC04's push-pull outputs, the 74HC05PW has open-drain outputs only. Substituting it for a 74HC04 will result in undefined HIGH states unless external pull-ups are added, and it cannot actively drive HIGH.

What is the maximum capacitive load the 74HC05PW,118 can drive reliably?

Based on dynamic characteristics and CPD = 4 pF per gate, the device supports ≤50 pF total load capacitance while maintaining specified propagation delays. Exceeding this increases rise time and may violate setup/hold timing in synchronous systems.

Is the exposed pad on the TSSOP14 package (SOT402-1) electrically connected?

No-the thermal pad on the 74HC05PW,118 is not internally connected to GND or any other node. Nexperia specifies it may remain floating or be soldered to a non-connected copper pour; if connected, it must not be tied to GND or VCC to avoid unintended current paths.
