74HC20N,652

Overview

The 74HC20N,652 is a dual 4-input NAND gate manufactured by NXP Semiconductors. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device complies with JEDEC standard JESD7A and features input clamp diodes for interfacing with voltages exceeding VCC. It provides low-power dissipation and robust ESD protection, exceeding 2000 V per HBM and 200 V per MM standards. The component is housed in a DIP-14 plastic dual in-line package (SOT27-1) designed for through-hole mounting.

Feature Summary

• Dual 4-input NAND logic function
• CMOS level input compatibility
• High electrostatic discharge protection capability
• Wide operating temperature range

Applications

• General digital logic processing
• Industrial control systems
• Consumer electronics circuitry

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product data sheet to ensure correct package type and temperature rating. Confirm that the component status aligns with project lifecycle requirements, as availability may change. Cross-reference the JEDEC compliance and ESD specifications with system design constraints before finalizing procurement decisions.

Selection Notes

Select this component when a dual 4-input NAND gate with CMOS input levels is required. Ensure the application voltage falls between 2.0 V and 6.0 V. Consider the DIP-14 package if through-hole assembly is necessary. Verify that the operating temperature range meets the environmental conditions of the intended deployment site.

Part Context

This part belongs to the 74HC/HCT logic family, which offers high-speed Si-gate CMOS technology compatible with low power Schottky TTL (LSTTL). The HC series specifically utilizes CMOS input levels, distinguishing it from the HCT variant which uses TTL levels. This family is widely used in general-purpose digital applications requiring reliable switching performance.

Replacement Considerations

Compatible alternatives include other manufacturers' 74HC20 devices in DIP-14 packages. Verify pinout compatibility and electrical characteristics such as propagation delay and output drive current before substitution.
