SN74LS37NSR

Inverter Gates Overview

The SN74LS37NSR is a quad two-input NAND buffer manufactured by Texas Instruments. It operates within the LS logic series and features an SOIC-14 surface-mount package. Key electrical parameters include a propagation delay of 12 ns, a low-level output current of 24 mA, and a high-level output current of -1.2 mA. The device functions with a supply voltage range of 4.75 V to 5.25 V and supports operating temperatures from 0°C to +70°C.

Inverter Gates Feature Summary

• Contains four independent two-input NAND gates configured as buffers
• Provides buffered outputs for improved signal integrity
• Compatible with standard TTL logic families

Inverter Gates Applications

• Digital logic circuit buffering
• Signal isolation in data transmission lines
• General-purpose logic gate applications

Inverter Gates Procurement Notes

Verify the specific ordering suffix to confirm the tape-and-reel packaging configuration intended for automated assembly processes. Ensure the component meets RoHS compliance requirements for your manufacturing standards. Confirm the manufacturer source directly through authorized channels to guarantee authenticity and traceability of the Texas Instruments product.

Inverter Gates Selection Notes

Select this component when a quad NAND buffer topology is required within the LS logic family constraints. Consider the SOIC-14 package dimensions for PCB layout compatibility. Evaluate the 12 ns propagation delay against system timing requirements to ensure adequate performance margins for the target digital application speed.

Inverter Gates Part Context

This part belongs to the SN74LS37 series of quad two-input NAND buffers. It is distinct from other SN74LS variants such as the SN74LS32 (OR gates) or SN74LS04 (inverters). The NSR suffix specifically denotes the SOIC-14 surface-mount package with reel packaging, differentiating it from through-hole DIP versions.

Inverter Gates Replacement Considerations

Check for direct equivalents like the SN74LS37N for through-hole applications. Verify pinout compatibility before substituting with other quad NAND buffers from different manufacturers.
