SN74HCS32DYYR

Inverter Gates Overview

The SN74HCS32DYYR is a quadruple 2-input OR gate featuring Schmitt-trigger inputs, manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an ambient temperature range from -40°C to +125°C. The device utilizes the SOT-23-THIN (DYY) package with 14 pins. Electrical characteristics include ±7.8 mA output drive capability at 6 V, typical input leakage current of ±100 nA, and propagation delays ranging from 6 ns to 36 ns depending on voltage. It offers low power consumption with a typical ICC of 100 nA.

Inverter Gates Feature Summary

• Schmitt-trigger inputs provide tolerance for slow or noisy signals
• Balanced CMOS push-pull outputs ensure similar sourcing and sinking currents
• Wide operating voltage range supports diverse system requirements
• Low power consumption minimizes static current draw

Inverter Gates Applications

• Monitoring error signals using fewer inputs
• Combining active-low enable signals
• Directly controlling fan driver enable pins via overheat signals

Inverter Gates Procurement Notes

Verify the specific DYY package designation when ordering to ensure correct physical footprint compatibility. Confirm that the design accounts for the thermal resistance values associated with the SOT-23-THIN package under expected load conditions. Ensure all unused inputs are terminated to prevent undefined operational states.

Inverter Gates Selection Notes

Select this component when noise immunity is critical due to its Schmitt-trigger architecture. It is suitable for applications requiring wide voltage operation between 2 V and 6 V. Consider the SOT-23-THIN package constraints regarding thermal dissipation and board space limitations compared to standard SOIC packages.

Inverter Gates Part Context

This part belongs to the SN74HCS series of high-speed CMOS logic devices. The HCS designation indicates the inclusion of Schmitt-trigger inputs, distinguishing it from standard HC or HCT logic families. It provides robust performance in electrically noisy environments while maintaining low power consumption typical of CMOS technology.

Inverter Gates FAQ

How should unused inputs be handled?

Unused inputs must not be left floating. They should be tied to either VCC or ground to prevent undefined operational states.

What is the maximum capacitive load recommended?

The device can drive a load with a total capacitance less than or equal to 50 pF while meeting all datasheet specifications.
