SN74LS38MR1

Inverter Gates Overview

The SN74LS38MR1 is an octal open-collector NAND gate manufactured by onsemi. It operates within a supply voltage range of 4.5 V to 5.5 V and supports propagation delays of up to 25 ns. The device features low-level output current capability of 8 mA and high-level output current of -400 µA. It functions reliably across an operating temperature range from 0 °C to 70 °C and is housed in a 16-pin SOIC package.

Inverter Gates Feature Summary

• Octal configuration providing eight independent open-collector NAND gates
• Open-collector outputs enable wired-AND logic connections and flexible voltage level interfacing
• Compatible with standard TTL logic families for seamless integration

Inverter Gates Applications

• Bus-oriented systems requiring open-collector drivers
• TTL-to-MOS interface circuits
• General-purpose digital logic applications

Inverter Gates Procurement Notes

Verify the manufacturer designation carefully, as the part number prefix 'SN' typically indicates Texas Instruments while the brand is listed as onsemi. Confirm that the specific suffix matches the required SOIC-16 package and tape-and-reel packaging format. Ensure the component meets the specified electrical characteristics for the LS series before finalizing procurement orders.

Inverter Gates Selection Notes

Select this component when an octal NAND gate with open-collector outputs is required for bus driving or voltage translation tasks. Consider the 8 mA sink current capability for load requirements. Verify compatibility with existing TTL logic levels and ensure the operating temperature range aligns with the system environment constraints.

Inverter Gates Part Context

This component belongs to the 74LS (Low-power Schottky) logic family, known for improved speed over standard TTL while maintaining low power consumption. The open-collector architecture distinguishes it from standard push-pull outputs, allowing for external pull-up resistors to define logic high levels.
