74HC20PW,112

Overview

The Nexperia 74HC20PW,112 is a dual 4-input NAND gate in a TSSOP14 package (SOT402-1). It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS low power dissipation and high noise immunity. Static characteristics include input leakage current up to ±1 μA at 6.0 V and supply current up to 40 μA at 125 °C. Dynamic performance shows propagation delays ranging from 8 ns to 135 ns depending on voltage and temperature.

Feature Summary

• Includes input clamp diodes for interfacing with voltages exceeding VCC using current limiting resistors.
• Provides ESD protection exceeding 2000 V via Human Body Model and 1000 V via Charged Device Model.
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B standards.

Applications

• Digital logic circuits requiring dual 4-input NAND functionality
• Systems operating within 2.0 V to 6.0 V supply ranges
• Industrial environments requiring operation from -40 °C to +125 °C

Procurement Notes

Verify the specific ordering suffix ,112 corresponds to the TSSOP14 package variant SOT402-1 as documented in the official Nexperia datasheet. Confirm that the required temperature range and voltage specifications align with the recommended operating conditions provided in the product data sheet before finalizing procurement orders.

Selection Notes

Select this component when a dual 4-input NAND gate is required in a thin shrink small outline package. Ensure the application design accounts for the specified propagation delay variations across the full temperature and voltage ranges. Verify that the load capacitance and input transition rates remain within the limits defined in the dynamic characteristics section of the datasheet.

Part Context

This part belongs to the 74HC series of high-speed CMOS logic devices manufactured by Nexperia. The 74HC20 specifically provides two independent 4-input NAND gates. The PW suffix indicates the TSSOP14 plastic package, distinguishing it from the SO14 variant. This series is designed for general-purpose digital applications requiring low power consumption and compatibility with standard CMOS logic levels.

Replacement Considerations

The 74HC20D is an alternative package version (SO14) of the same logical function. Cross-referencing pinouts and thermal derating curves is necessary when substituting between TSSOP14 and SO14 packages due to differences in total power dissipation ratings.
