SN74LS11DR2

Inverter Gates Overview

The SN74LS11DR2 is a triple 3-input AND gate manufactured by onsemi, belonging to the LS (Low-power Schottky) logic series. It features three independent gates within a single package, providing nine inputs and three outputs. The device operates with a supply voltage range of 4.5 V to 5.5 V and supports output currents of up to 8 mA for both high and low states. It is designed for operation across an extended temperature range from -40°C to +85°C.

Inverter Gates Feature Summary

• Triple 3-input AND logic functionality
• Low-power Schottky (LS) technology for reduced power consumption
• Standard TTL-compatible input and output levels

Inverter Gates Applications

• Digital logic circuit design
• Signal gating and masking
• Control logic in industrial systems

Inverter Gates Procurement Notes

Verify the manufacturer marking carefully, as onsemi produces this part under license or acquisition. Confirm the suffix 'DR2' indicates the SOIC-14 tape-and-reel packaging. Ensure RoHS compliance status matches current regulatory requirements for your region. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Inverter Gates Selection Notes

Select this component when low-power dissipation is critical compared to standard TTL. It offers faster switching speeds than standard LS devices while maintaining lower power usage. Consider the SOIC-14 package size for PCB layout constraints. Verify that the 5V supply voltage aligns with the rest of the system logic levels.

Inverter Gates Part Context

This part is part of the widely used 74xx series of logic ICs. The LS variant specifically balances speed and power efficiency. It is commonly found in legacy and modern digital designs requiring reliable AND operations. The DR2 suffix denotes surface-mount packaging suitable for automated assembly processes.

Inverter Gates Replacement Considerations

Direct pin-to-pin replacements include other manufacturers' SN74LS11 parts. Check for equivalent LS-series alternatives from Texas Instruments or NXP if supply chain issues arise. Ensure voltage and current ratings match exactly to avoid signal integrity problems.
