SN74LS11DR

Inverter Gates Overview

The SN74LS11DR is a triple 3-input positive-AND gate integrated circuit manufactured by Texas Instruments. It belongs to the LS (Low-power Schottky) logic family and features a non-inverting function with three independent channels, each accepting three inputs. The device is housed in a 14-pin SOIC surface-mount package. Key electrical specifications include a propagation delay of 10 ns at 5 V, a low-level output current of 8 mA, and a high-level output current of -400 uA. It operates within a supply voltage range of 4.75 V to 5.25 V and supports an operating temperature range from 0°C to +70°C.

Inverter Gates Feature Summary

• Triple 3-input AND logic configuration for complex boolean operations
• Low-power Schottky technology ensuring high speed with reduced power consumption
• Open-collector compatible output structure suitable for wired-logic applications

Inverter Gates Applications

• Digital logic control systems requiring multi-input decision making
• Microprocessor interface circuits for address decoding
• General-purpose digital signal processing gates

Inverter Gates Procurement Notes

Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging format when ordering. Confirm that the required propagation delay and output current specifications meet the target circuit design constraints. Ensure compatibility with standard 5V logic levels and check for RoHS compliance requirements relevant to the manufacturing region.

Inverter Gates Selection Notes

Select this component when a compact solution for multiple 3-input AND functions is required in space-constrained designs. The LS series offers a balance between speed and power efficiency compared to standard TTL. Consider the SOIC package dimensions for PCB layout planning and ensure thermal dissipation capabilities are adequate for the expected operating environment.

Inverter Gates Part Context

This part is part of the broader SN74xx logic family, widely used in industrial and consumer electronics. The SN74LS11 specifically provides triple 3-input AND functionality, distinguishing it from single or dual input variants. It serves as a fundamental building block for combinational logic circuits in legacy and modern embedded systems.

Inverter Gates Replacement Considerations

Compatible substitutes include the SN74LS11N (DIP package) for through-hole applications. Other equivalents may include parts from manufacturers like ON Semiconductor or NXP, provided they match the LS logic family specifications and pinout configuration.
