Overview
The National Semiconductor 74H05PC is a hex inverter integrated circuit featuring open-drain outputs. It operates within a supply voltage range of 2.0 V to 6.0 V and complies with JEDEC standard no. 7A. The device contains six inverters with inputs compatible with CMOS logic levels. It provides latch-up performance exceeding 100 mA per JESD 78 Class II and includes ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). The component is specified for operation from -40 °C to +85 °C and up to +125 °C.
Feature Summary
- Hex inverter configuration with open-drain outputs suitable for wired-OR or wired-AND functions
- Wide operating voltage range supporting 2.0 V to 6.0 V applications
- High noise immunity and robust latch-up protection exceeding 100 mA
Applications
- Bus-oriented systems requiring active-HIGH wired-AND or active-LOW wired-OR logic
- Open-drain output driving for interfacing with different logic families
- General-purpose inversion in digital control circuits
Procurement Notes
Verify the manufacturer origin, as National Semiconductor is now part of Texas Instruments. Confirm the package type matches the required PCB footprint. Ensure the specific temperature grade meets the operational environment requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this component when open-drain outputs are necessary for wired logic connections or level shifting between different voltage domains. The wide voltage range allows flexibility in power supply design. Consider the thermal specifications if the application involves high ambient temperatures or significant self-heating.
Part Context
This component belongs to the 74Hxx series of high-speed CMOS logic devices. The 'H' indicates high-speed performance compared to standard HC series, while the '05' denotes the hex inverter function with open-drain outputs. This family is widely used in general-purpose digital electronics for signal conditioning and interface management.
