SN74HC05PWT

Overview

The SN74HC05PWT is a hex inverter integrated circuit from Texas Instruments, belonging to the HC logic family. 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 2V to 6V and supports an operating temperature range from -40°C to +125°C. Key electrical characteristics include a maximum propagation delay of 20ns at 6V with 50pF load and a low-level output current capability of 5.2mA.

Feature Summary

• Hex inverter configuration with open-drain outputs for flexible interfacing
• Wide operating supply voltage range supporting 2V to 6V applications
• Extended industrial temperature rating up to +125°C for harsh environments
• Surface-mount TSSOP-14 packaging for compact board integration

Applications

• General-purpose digital signal inversion in consumer electronics
• Interface buffering between different logic voltage levels
• Open-drain driving for bus systems requiring wired-AND functionality
• Signal conditioning in industrial control modules

Procurement Notes

Verify the exact suffix 'PWT' corresponds to the TSSOP-14 package and tape-and-reel shipping format. Confirm the manufacturer is Texas Instruments, as generic HC05 parts may lack specific performance guarantees. Check RoHS compliance status if required for your assembly process. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when open-drain output capability is required for level shifting or bus sharing. The HC series offers higher speed than standard HCT while maintaining CMOS input compatibility. Consider the TSSOP-14 package size constraints and thermal dissipation requirements for high-density designs. Verify that the 2V minimum supply voltage meets your system's lowest operating condition.

Part Context

This part belongs to the SN74HCxx series of high-speed CMOS logic devices. It is functionally similar to other hex inverters but distinguished by its open-drain output structure, which differs from standard push-pull outputs found in devices like the SN74HC04. The PWT suffix indicates the specific physical package and reel packaging method used by the manufacturer.

FAQ

What is the difference between SN74HC05 and SN74HC04?

The SN74HC05 features open-drain outputs, allowing it to drive loads at voltages higher than VCC and support wired-AND configurations. The SN74HC04 has standard push-pull outputs that cannot exceed the supply voltage.

Can the SN74HC05PWT operate at 3.3V?

Yes, the device operates within a supply voltage range of 2V to 6V, making it fully compatible with 3.3V logic systems.
