SN74LS03NSR

Inverter Gates Overview

The SN74LS03NSR is a quadruple 2-input positive-NAND gate with open-collector outputs manufactured by Texas Instruments. It operates within a supply voltage range of 4.75V to 5.25V and features a propagation delay of 32ns at 5V with 15pF load. The device supports low-level output current of 16mA and high-level output current of 250µA, with logic levels defined as 0.8V for low and 2V for high. Designed for through-hole mounting in a 14-PDIP package, it functions reliably across an operating temperature range of 0°C to 70°C.

Inverter Gates Feature Summary

• Contains four independent 2-input NAND gates performing positive-logic Boolean operations

Inverter Gates Procurement Notes

Verify the specific suffix 'SR' against official Texas Instruments documentation to confirm tape-and-reel packaging and exact manufacturing lot details. Ensure compatibility with existing PCB footprints for the 14-PDIP form factor. Cross-reference RoHS compliance status and lead-free specifications with the latest datasheet revisions before finalizing procurement orders.

Inverter Gates Selection Notes

Select this component when open-collector NAND gates are required for wired-AND applications or interfacing with higher voltage loads. The LS series offers a balance of speed and power consumption suitable for general-purpose digital logic. Verify that the 16mA sink capability meets the load requirements of the connected circuitry.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74LS series of logic integrated circuits, which utilizes Low-power Schottky technology. The SN74LS03 variant specifically provides quadruple 2-input NAND gates with open-collector outputs, distinguishing it from standard push-pull output variants like the SN74LS00.

Inverter Gates Replacement Considerations

Direct substitutes include SN74LS03N and SN74LS03DR. Verify pinout compatibility and electrical parameters such as propagation delay and output drive strength before substitution.
