74H00PC

Overview

The National Semiconductor 74H00PC is a quad 2-input NAND gate implemented in high-speed silicon-gate CMOS technology. It operates within a supply voltage range of 2.0 V to 6.0 V and provides symmetrical output impedance with low power dissipation. The device features balanced propagation delays and complies with JEDEC standard no. 8-1A. It includes ESD protection exceeding 2000 V (HBM) and 200 V (MM). Operating temperatures are specified from -40 °C to +85 °C or +125 °C depending on the variant.

Feature Summary

• High-speed silicon-gate CMOS construction
• Wide supply voltage operation from 2.0 V to 6.0 V
• Symmetrical output impedance for balanced performance

Procurement Notes

Verify the specific suffix code against official datasheets to confirm temperature range and package tolerance. Ensure the component matches the required JEDEC compliance level. Check RoHS status as older batches may differ. Confirm pinout compatibility if replacing legacy parts. Validate manufacturer documentation for any obsolescence notices.

Selection Notes

Select this component when a standard quad NAND function is required in a CMOS environment. It serves as a drop-in replacement for LSTTL designs due to pin compatibility. Consider the wide voltage range for mixed-signal systems. Evaluate power consumption requirements against other logic families. Verify operating temperature needs for industrial applications.

Part Context

This part belongs to the 74H series, representing high-speed CMOS logic. It is functionally equivalent to the 74HC00 but may carry specific National Semiconductor manufacturing attributes. The 'PC' suffix typically denotes a plastic DIP package. It is widely used in general-purpose digital electronics and industrial control systems.

Replacement Considerations

Direct substitutes include 74HC00 variants from NXP, ON Semiconductor, and Diodes Incorporated. Ensure voltage and temperature ratings match the original design constraints. Verify package dimensions for mechanical fit.
