SN74H20N

Overview

The SN74H20N is a quad 2-input positive-NAND gate manufactured by Texas Instruments. It belongs to the HC logic family and utilizes CMOS technology. The device operates within a supply voltage range of 2 V to 6 V. It features push-pull outputs with a maximum low-level output current of 5.2 mA and a maximum high-level output current of -5.2 mA. Propagation delay is typically 18 ns at 4.5 V and 15 ns at 6 V, with a maximum absolute delay of 115 ns. The component supports an operating temperature range from -40°C to +85°C and is housed in a 14-pin PDIP package.

Feature Summary

Contains four independent 2-input NAND gates within a single integrated circuit.
Utilizes standard CMOS process technology for compatibility with TTL inputs.
Features push-pull output stages capable of driving moderate loads.

Applications

Digital logic signal processing
General-purpose switching circuits
Input buffering for microprocessor systems

Procurement Notes

Verify the specific suffix 'N' indicates the PDIP-14 through-hole package variant. Confirm RoHS compliance status as required by project specifications. Ensure the ordering part number matches the exact logic family (HC) and function (NAND) to avoid substitution errors with similar series like HCT or LS.

Selection Notes

Select this component when a quad 2-input NAND configuration is required in a through-hole format. The HC family offers higher speed than standard LS logic while maintaining low power consumption. Verify that the 5.2 mA drive current meets the load requirements of the connected circuitry before finalizing the design.

Part Context

This device is part of the broader SN74xx logic family, specifically the High-speed CMOS (HC) sub-family. It serves as a fundamental building block for digital electronics, providing basic Boolean logic operations. The HC series is designed to be pin-compatible with earlier transistor-transistor logic (TTL) standards, facilitating migration in existing designs.
