SN74S37N

Inverter Gates Overview

The SN74S37N is a quad 2-input NAND buffer manufactured by Texas Instruments, belonging to the 74S logic series. It features Schottky-clamped transistors for high-speed operation with a propagation delay of 6 ns. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a low-level output current of 60 mA and a high-level output current of -3 mA. It is housed in a 14-pin PDIP package and functions reliably across an operating temperature range of 0°C to +70°C.

Inverter Gates Feature Summary

• Integrates four independent 2-input NAND gates within a single package
• Utilizes Schottky technology to achieve high switching speeds
• Provides robust low-level sink current capability for driving loads

Inverter Gates Applications

• High-speed digital signal buffering
• Pulse generation circuits
• General-purpose logic gating in industrial control systems

Inverter Gates Procurement Notes

Verify the specific manufacturer lot code and RoHS compliance status against the latest datasheet revision, as legacy components may have varying environmental certifications. Confirm that the PDIP-14 package dimensions match your PCB footprint requirements. Ensure the supply voltage remains strictly within the 4.75 V to 5.25 V range to prevent device damage or performance degradation during operation.

Inverter Gates Selection Notes

Select this component when Schottky speed is required over standard TTL or LS variants. The SN74S37N offers faster propagation delays compared to non-Schottky equivalents but consumes more power. Consider thermal management due to higher static current draw inherent to the S-series logic family. Verify compatibility with existing system voltage levels before integration into new designs.

Inverter Gates Part Context

This part belongs to the Texas Instruments 74S (Schottky) logic family, designed for applications requiring faster switching speeds than standard 7400 series devices. The SN74S37N specifically implements NAND logic functions. It serves as a bridge between older TTL standards and modern high-speed requirements, though it has largely been superseded by newer AC/ACT families in contemporary designs.
