SN74HC05APWR

Overview

The SN74HC05APWR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the HC (High-speed CMOS) logic family. It features six independent inverters with open-drain outputs, designed for surface-mount applications in a TSSOP-14 package. The device operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include a maximum static current of 2 µA and output drive capabilities of ±5.2 mA at both high and low states. Propagation delay is specified at 20 ns when measured at 6 V with a 50 pF load.

Feature Summary

• Hex inverter configuration providing six independent signal inversion channels
• Open-drain output architecture suitable for wired-OR configurations and level shifting
• CMOS technology ensuring low static power consumption and high noise immunity

Applications

• General-purpose digital signal inversion in consumer electronics
• Memory interface buffering where open-drain pull-up flexibility is required
• Microcontroller peripheral interfacing for voltage level translation

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official documentation to confirm pinout compatibility and electrical specifications relative to standard variants. Ensure the TSSOP-14 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the latest datasheet revision notes before finalizing procurement orders.

Selection Notes

Select this component when a hex inverter with open-drain outputs is required for HC logic speed and voltage ranges. It is appropriate for designs needing flexible output loading or multi-voltage domain interfacing. Consider the TSSOP-14 package size constraints and ensure thermal management aligns with the specified operating temperature range for your application environment.

Part Context

This part belongs to the widely adopted 74HC series of high-speed CMOS logic devices. The HC series offers performance comparable to the older LS-TTL family while maintaining lower power consumption. The inclusion of open-drain outputs distinguishes it from standard push-pull inverters, allowing for greater versatility in bus structures and interconnect topologies within digital systems.

Replacement Considerations

SN74HC05PWR: Standard commercial grade variant in similar packaging. SN74HC05N: Through-hole DIP alternative offering identical logical functionality but different mounting style.
