74ABT20D,112

Inverter Gates Overview

The NXP USA Inc. 74ABT20D,112 is a dual 4-input NAND gate manufactured using high-performance BiCMOS technology. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +85 °C. The device features low static and dynamic power dissipation combined with high speed and high output drive capabilities. Propagation delays are specified at 3.9 ns (LOW to HIGH) and 3.4 ns (HIGH to LOW) under standard test conditions. Input clamping voltage is rated at -1.2 V, and the package is the SO14 plastic small outline package (SOT108-1).

Inverter Gates Feature Summary

Inverter Gates Procurement Notes

Verify the specific ordering suffix '112' corresponds to the tube packaging format as defined in the official Nexperia documentation. Confirm that the SO14 package variant matches the required board layout dimensions. Ensure compatibility with the 4.5 V to 5.5 V supply voltage requirements for the target application environment.

Inverter Gates Selection Notes

Select this component when a dual 4-input NAND gate is required within the 74ABT logic family. The BiCMOS technology offers superior speed and drive strength compared to standard CMOS alternatives. Consider the SO14 package constraints if space is limited, noting the 3.9 mm body width specification for PCB footprint design.

Inverter Gates Part Context

The 74ABT20 belongs to the 74ABT series of high-speed BiCMOS logic devices produced by Nexperia, which was formed from the merger of Philips Semiconductors and NXP's Standard Products division. This series is designed for applications demanding high performance and low power consumption. The 'D' suffix indicates the SO14 package type, while '112' denotes the specific tape and reel or tube configuration provided by the manufacturer.

Inverter Gates Replacement Considerations

Direct substitutes include other 74ABT20 variants such as the 74ABT20DB (SSOP14) or 74ABT20PW (TSSOP14), provided the package footprint can be adapted. Cross-family replacements like 74HC20 or 74HCT20 may be considered if speed requirements are relaxed, though electrical characteristics will differ significantly.
