SN74LS26N

Inverter Gates Overview

The SN74LS26N is a quadruple 2-input positive NAND gate manufactured by Texas Instruments. It features open-collector outputs designed for high-voltage interface applications. The device operates within a supply voltage range of 4.75V to 5.25V. Key electrical parameters include a maximum output current of 8mA and an input logic level low threshold of 0.8V. It is housed in a 14-pin PDIP package and supports through-hole mounting.

Inverter Gates Feature Summary

• Quad 2-input positive NAND gate configuration
• Open-collector output structure for high-voltage interfacing
• Compatible with standard LS logic families

Inverter Gates Applications

• High-voltage digital interface circuits
• Logic gating in TTL-based systems
• Wired-OR logic implementation

Inverter Gates Procurement Notes

Verify the specific manufacturer suffix and date code against official Texas Instruments documentation to ensure authenticity. Confirm that the open-collector output requirement aligns with your circuit design, as this variant differs from standard push-pull NAND gates. Check for RoHS compliance status if required by your manufacturing standards.

Inverter Gates Selection Notes

Select the SN74LS26N when open-collector outputs are necessary for driving loads at voltages higher than the standard logic supply. Ensure pull-up resistors are correctly sized for the desired switching speed and load current. Compare with standard SN74LS00 variants only if high-voltage tolerance or wired-logic capability is explicitly required by the schematic.

Inverter Gates Part Context

This component belongs to the Texas Instruments SN74LS series of low-power Schottky TTL logic devices. The SN74LS26N specifically provides quad 2-input NAND gates with open-collector outputs, distinguishing it from standard NAND gates like the SN74LS00 which feature push-pull outputs. It is part of the broader family of discrete logic ICs used in digital electronics.
