Overview
The Nexperia 74HC20D,652 is a dual 4-input NAND gate integrated circuit belonging to the 74HC logic family. It operates within a supply voltage range of 2.0 V to 6.0 V and features CMOS low power dissipation with high noise immunity. The device includes input clamp diodes for interfacing with voltages exceeding VCC via current-limiting resistors. Latch-up performance exceeds 100 mA per JESD 78 Class II Level B. It complies with JEDEC standards JESD8C (2.7 V to 3.6 V) and JESD7A (2.0 V to 6.0 V). ESD protection meets ANSI/ESDA/JEDEC JS-001 class 2 (>2000 V HBM) and JS-002 class C3 (>1000 V CDM).
Feature Summary
- Dual 4-input NAND gate configuration in the 74HC logic family.
- Wide supply voltage operation from 2.0 V to 6.0 V.
- Input clamp diodes enable safe interfacing with voltages above VCC.
Applications
- General-purpose digital logic applications requiring NAND functionality.
- Mixed voltage environments utilizing input clamp diodes.
- Systems requiring high noise immunity and low power consumption.
Procurement Notes
Verify component authenticity through authorized Nexperia distributors or direct sales channels. Confirm package type and marking codes match official datasheet specifications. Check for RoHS compliance status and ensure storage conditions adhere to moisture sensitivity level requirements. Validate that the specific suffix corresponds to the desired packaging format before finalizing procurement orders.
Selection Notes
Select this component when a dual 4-input NAND gate is required within the 74HC family. Ensure the operating voltage aligns with the 2.0 V to 6.0 V range. Consider the input clamp diode feature if interfacing with signals exceeding the supply voltage. Verify that the package dimensions and pinout meet the PCB layout constraints.
Part Context
This part belongs to the Nexperia 74HC series, which offers high-speed CMOS operation compatible with standard TTL levels. The 74HC20 specifically provides two independent 4-input NAND gates. It is designed for general-purpose digital applications where low power and high noise immunity are critical. The device supports a wide temperature range and robust ESD protection capabilities.
Replacement Considerations
Cross-reference with other manufacturers offering equivalent 74HC20 logic gates. Verify pin compatibility and electrical characteristics such as propagation delay and output current. Ensure the alternative component meets the same JEDEC standards and ESD protection levels. Check for availability and lead times if the original part is discontinued.
