SN74S37NSR

Inverter Gates Overview

The SN74S37NSR is a quad 2-input NAND buffer manufactured by Texas Instruments. It belongs to the SN54/74S logic series and features Schmitt-trigger inputs for noise immunity. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports a propagation delay of 6 ns at 5 V with 150 pF load. It provides a low-level output current of 60 mA and a high-level output current of -3 mA. The component is housed in a 14-SOIC surface-mount package and functions over an operating temperature range of 0°C to +70°C.

Inverter Gates Feature Summary

• Features Schmitt-trigger inputs to provide improved noise immunity and cleaner signal transitions.
• Provides buffered outputs capable of driving higher loads compared to standard logic gates.
• Delivers fast switching speeds suitable for high-frequency digital applications.

Inverter Gates Applications

• Signal buffering in digital communication interfaces
• Wave shaping and pulse generation circuits
• Clock distribution networks requiring clean signal edges

Inverter Gates Procurement Notes

Verify that the specific ordering suffix matches the required package type and lead finish. Confirm the Moisture Sensitivity Level rating aligns with your assembly process capabilities. Ensure the operating temperature range meets the environmental requirements of the final system design. Cross-reference the manufacturer part number against the latest datasheet to confirm active status and availability.

Inverter Gates Selection Notes

Select this component when Schmitt-trigger functionality is required for noisy environments or slow-rising signals. The S-series technology offers faster performance than LS variants but consumes more power. Verify that the 60 mA sink capability is sufficient for the connected load. Consider the SOIC package dimensions for PCB layout constraints.

Inverter Gates Part Context

This device is part of the Texas Instruments SN54/74S family, which utilizes Schottky-clamped transistor-transistor logic (TTL) technology. This family was designed to offer a balance between speed and power consumption relative to earlier standard TTL families. The SN74S37 specifically implements non-inverting buffer configurations with Schmitt triggers on all inputs.

Inverter Gates Replacement Considerations

SN74S37D is a parameter-equivalent alternative available in a similar SOIC package format from Texas Instruments.
