Description

Product Overview

The 74HC05D,118 from Nexperia is a hex inverter with open-drain outputs in a 14-pin SOIC package. The open-drain outputs enable wired-OR logic, level translation, and bus driving with external pull-up resistors to any voltage up to 6V.

Key Specifications

Function	Hex inverter (open-drain)
Supply Voltage	2.0V to 6.0V
Propagation Delay	12 ns at 5V
Output Type	Open-drain
Output Drive	±5.2 mA sink
Package	SOIC-14 (3.9×8.65mm)

Working Principle

Each of the six inverters has an open-drain N-channel output. When the input is HIGH, the output transistor is ON (LOW). When the input is LOW, the output is floating (HIGH-Z), requiring an external pull-up resistor. This enables wired-OR connections where multiple outputs share a common pull-up, and level translation when pull-ups are connected to a different supply rail.

Applications

Wired-OR bus (I2C-like)
Level translation
