SN74LV21ADE4

Inverter Gates Overview

The SN74LV21ADE4 is a dual 4-input positive-AND gate manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features outputs capable of sourcing and sinking 12 mA. The device is housed in a 14-pin Small Outline Integrated Circuit (SOIC) package with a standard .25-inch width. It supports an operating temperature range from -40°C to +85°C, ensuring reliable performance in industrial environments.

Inverter Gates Feature Summary

• Provides two independent 4-input AND logic functions for complex signal processing
• Supports wide supply voltage operation from 2 V to 5.5 V for flexible system integration
• Delivers high drive current capability of 12 mA on both high and low output states

Inverter Gates Applications

• Digital signal detection circuits requiring precise logic state identification
• Microcontroller input conditioning and interface logic
• General-purpose digital logic systems utilizing 3.3 V or 5 V power rails

Inverter Gates Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and environmental compliance. Confirm the package type matches the required PCB footprint. Ensure the operating temperature grade meets the application's thermal requirements. Cross-reference the manufacturer's latest datasheet revision for any pinout or electrical characteristic updates before finalizing procurement specifications.

Inverter Gates Selection Notes

Select this component when dual 4-input AND functionality is required within a compact SOIC package. It is suitable for designs needing robust drive strength at lower voltages compared to standard CMOS families. Consider the 2 V minimum supply voltage if powering from single-cell lithium sources or regulated 3.3 V rails. Verify that unused inputs are properly terminated to prevent floating states.

Inverter Gates Part Context

This part belongs to the SN74LV series, designed for low-voltage CMOS applications. It offers improved switching speeds and lower power consumption compared to older logic families. The device is compatible with various digital systems requiring reliable Boolean logic operations under varying supply conditions.

Inverter Gates Replacement Considerations

Check for direct pin-compatible alternatives within the same logic family. Verify that substitute parts maintain the 12 mA output drive capability and 2 V to 5.5 V operating range. Ensure the replacement package matches the 14-SOIC form factor.
