74ABT20DB,112

Overview

The 74ABT20DB,112 is a dual 4-input NAND gate integrated circuit manufactured by Nexperia USA Inc. It belongs to the ABT logic series and is housed in a 14-pin SSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical characteristics include a propagation delay of 8 ns, a low-level output current of 5.2 mA, and a high-level output current of -5.2 mA. It supports surface mount installation and functions reliably across an operating temperature range from -40 °C to +125 °C.

Feature Summary

• Dual configuration providing two independent 4-input NAND logic gates
• ABT technology ensures fast switching speeds with low power consumption
• Wide operating temperature range suitable for industrial environments

Applications

• Digital signal processing circuits requiring NAND logic operations
• Microprocessor-based systems for address decoding or control logic
• General-purpose digital logic applications in consumer electronics

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as required by specific project regulations. Check for end-of-life notifications or discontinuation notices from Nexperia prior to finalizing procurement plans. Ensure packaging specifications match assembly line requirements.

Selection Notes

Select this component when dual 4-input NAND functionality is required in a compact SSOP package. The ABT series offers superior speed compared to standard HC logic families while maintaining compatibility with 5V systems. Consider thermal management capabilities if operating near the upper temperature limit of 125 °C.

Part Context

This part is part of Nexperia's extensive portfolio of logic ICs designed for general-purpose digital applications. The 74ABT20 variant specifically addresses needs for high-speed NAND operations in space-constrained designs. It complements other ABT series components like inverters and OR gates for complete logic system implementation.

Replacement Considerations

Direct substitutes may include equivalent parts from other manufacturers offering dual 4-input NAND gates in SSOP-14 packages with similar electrical characteristics. Verify pinout compatibility and voltage ranges before substitution.
