SN74HC05APW

Overview

The SN74HC05APW is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the 74HC logic family. It features six independent inverters within a single package. The device operates with a supply voltage range of 2V to 6V and supports input levels compatible with standard CMOS and TTL logic families. It utilizes an open-drain output configuration, requiring external pull-up resistors for proper high-state operation. The component is housed in a 14-pin TSSOP surface-mount package and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Hex inverter architecture providing six independent signal inversion channels
• Open-drain output structure allowing flexible interfacing with various load types
• CMOS technology ensuring low static power consumption during steady states
• Wide supply voltage compatibility supporting both 3.3V and 5V logic systems

Applications

• Signal level translation between different voltage domains
• Driving high-capacitance or current-sinking loads via external pull-ups
• General-purpose digital logic inversion in consumer electronics
• Interface circuits requiring wired-AND logic configurations

Procurement Notes

Verify the specific suffix 'APW' corresponds to the TSSOP-14 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to procurement. Ensure the ordering part number matches the required pinout and electrical specifications exactly to avoid integration errors in final assembly.

Selection Notes

Select this component when open-drain outputs are required for driving non-standard loads or implementing wired-logic functions. It is suitable for designs needing wide voltage flexibility between 2V and 6V. Consider alternative packages if board space constraints differ from the TSSOP-14 footprint. Verify that the application does not require push-pull outputs, as this device lacks internal pull-up structures.

Part Context

This part belongs to the SN74HC series of high-speed CMOS logic devices produced by Texas Instruments. The HC series is widely used in general-purpose digital applications due to its speed and power efficiency. The SN74HC05 specifically provides open-drain outputs, distinguishing it from standard push-pull inverters like the SN74HC04. It serves as a key component in mixed-voltage interface designs.

FAQ

What is the difference between SN74HC05 and SN74HC04?
