SN74LS05DR

Inverter Gates Overview

The SN74LS05DR is a hex inverter integrated circuit manufactured by Texas Instruments, belonging to the 74LS logic series. It features six independent inverters with open-collector outputs housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a low-level output current of 8 mA. Typical propagation delay is 32 ns at 5 V with 15 pF load capacitance. It functions reliably across an operating temperature range of 0°C to +70°C.

Inverter Gates Feature Summary

• Contains six independent inverter channels for signal inversion applications
• Equipped with open-collector outputs suitable for wired-AND configurations
• Supports standard TTL input levels and provides high noise immunity

Inverter Gates Applications

• Digital signal inversion in logic circuits
• Wired-AND bus line interfacing
• Open-collector driver applications requiring external pull-up resistors

Inverter Gates Procurement Notes

Verify the specific suffix 'DR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supplier source matches Texas Instruments or authorized distributors to guarantee component authenticity and traceability.

Inverter Gates Selection Notes

Select this component for designs requiring multiple inverted signals with open-collector flexibility. Consider the 8 mA sink capability for driving moderate loads. Verify that the required operating temperature range aligns with the commercial grade specification of 0°C to +70°C.

Inverter Gates Part Context

This part belongs to the widely adopted 74LS (Low-power Schottky) family, known for balancing speed and power consumption. The SN74LS05 variant specifically addresses applications needing open-collector outputs, distinguishing it from standard push-pull inverters like the SN74LS04.

Inverter Gates Replacement Considerations

Compatible substitutes include SN74LS05N (DIP package), SN74LS05NSR (tape-and-reel), and SN74LS05DG4 (lead-free variant). Cross-reference datasheets to ensure pinout and electrical characteristics match.
