SN74LS37N

Inverter Gates Overview

The SN74LS37N is a quad 2-input NAND gate integrated circuit manufactured by Texas Instruments. It belongs to the 74LS logic series and features open-collector outputs, which require external pull-up resistors for proper operation. The device is housed in a 14-pin Plastic Dual In-line Package (PDIP). It operates within a supply voltage range of 4.75V to 5.25V and supports a standard operating temperature range from 0°C to 70°C.

Inverter Gates Feature Summary

• Contains four independent 2-input NAND logic gates
• Features open-collector output configuration requiring external pull-up components
• Compatible with standard TTL logic families

Inverter Gates Applications

• Digital logic signal processing
• Interface circuits requiring wired-AND configurations
• General-purpose switching applications

Inverter Gates Procurement Notes

Verify the package type matches the required footprint, as this component is available in both through-hole PDIP and surface-mount SOIC variants. Confirm that the specific order suffix corresponds to the desired packaging format. Ensure the application design accounts for the open-collector nature of the outputs, necessitating appropriate external pull-up resistor selection for correct voltage levels.

Inverter Gates Selection Notes

Select this component when a quad 2-input NAND gate with open-collector outputs is required. It is suitable for designs needing wired-AND functionality or interfacing with higher voltage loads via pull-up networks. Consider alternative packages such as the SN74LS37NSR for surface-mount assembly requirements while maintaining identical logical functionality.

Inverter Gates Part Context

This part is a member of the Texas Instruments 74LS family, known for low-power Schottky logic performance. It serves as a fundamental building block for digital systems, providing basic Boolean NAND operations. The open-collector variant distinguishes it from standard push-pull outputs, offering flexibility in bus structures and level shifting.
