SN74LS03N

Inverter Gates Overview

The SN74LS03N is a quad two-input NAND gate integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 4.75V to 5.25V and features open-collector outputs. The device supports low-voltage input thresholds of 0.8V for logic low and 2V for logic high, with output current capabilities of 16mA (low) and 250µA (high). Propagation delay is specified at 32ns under 5V supply and 15pF load conditions. It functions reliably in ambient temperatures from 0°C to 70°C and is housed in a standard 14-pin dual in-line package.

Inverter Gates Feature Summary

Inverter Gates Procurement Notes

Verify the specific manufacturer part number SN74LS03N against official Texas Instruments documentation to confirm pinout, electrical characteristics, and package dimensions. Ensure compatibility with required operating temperature ranges and voltage specifications before integration into final designs.

Inverter Gates Selection Notes

Select this component when open-collector NAND functionality is required within standard 5V TTL logic families. Consider the 14-PDIP package for through-hole mounting requirements and verify that the 32ns propagation delay meets the timing constraints of the target application.

Inverter Gates Part Context

This device belongs to the Texas Instruments 74LS series of logic integrated circuits. The 74LS family utilizes Low-power Schottky technology to provide improved speed and power consumption characteristics compared to earlier standard TTL variants while maintaining compatible logic levels.
