SN74HC05PWR

Overview

The SN74HC05PWR is a hex inverter integrated circuit from Texas Instruments, belonging to the HC logic series. It features six independent inverters with open-drain outputs, housed in a 14-pin TSSOP package. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -40°C to +85°C. Designed for CMOS technology, it provides high noise immunity and low power consumption suitable for general-purpose digital applications.

Feature Summary

• Hex inverter configuration with open-drain output capability
• CMOS construction ensuring low static power consumption
• Wide operating voltage range supporting 2 V to 6 V systems

Applications

• General-purpose digital signal inversion
• Open-drain bus interface circuits
• Level shifting between different voltage domains

Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the TSSOP-14 package and tape-and-reel shipping format. Confirm RoHS compliance status and manufacturing origin through official Texas Instruments documentation or authorized distributor datasheets prior to procurement.

Selection Notes

Select this component when open-drain outputs are required for wired-AND configurations or level translation. Ensure the input voltage levels remain within the specified limits relative to VCC. Verify that the load capacitance does not exceed specifications to maintain signal integrity at desired switching speeds.

Part Context

This part belongs to the SN74HCxx family of high-speed CMOS logic devices. It serves as an inverting variant within the series, distinct from non-inverting buffers like the SN74HC04. The open-drain architecture differentiates it from standard push-pull outputs found in other logic gates.

Replacement Considerations

Compatible substitutes include SN74AHC05PWR for improved speed and SN74LV05APWR for extended temperature ranges. Verify pin compatibility and electrical characteristics against original requirements before substitution.
