74HCT32DTR2G

Inverter Gates Overview

The onsemi 74HCT32DTR2G is a quad 2-input OR gate featuring LSTTL-compatible inputs and high-performance silicon-gate CMOS technology. It operates within a DC supply voltage range of 4.5 to 5.5 V and supports an operating temperature from -55°C to +125°C. The device provides an output drive capability of 10 LSTTL loads, with maximum propagation delays of 15 ns at 4.5 V and 19 ns at 85°C under a 50 pF load. It utilizes a 14-lead TSSOP package.

Inverter Gates Feature Summary

• Features TTL/NMOS-compatible input levels for direct interfacing with CMOS, NMOS, and TTL logic families.
• Provides robust noise immunity characteristic of CMOS devices while maintaining compatibility with standard logic loads.
• Includes built-in protection circuitry against electrostatic discharge (ESD) exceeding 2000 V via human body model testing.

Inverter Gates Applications

• Digital signal processing circuits requiring logical OR operations
• Interface modules connecting TTL or NMOS systems to CMOS logic networks
• General-purpose logic control in industrial equipment

Inverter Gates Procurement Notes

Verify the specific suffix 'DTR2G' corresponds to the TSSOP-14 package configuration rather than the SOIC-14 variant. Confirm RoHS compliance status as the datasheet indicates lead-free construction. Ensure the ordering quantity aligns with the standard tape and reel shipping specifications provided by the manufacturer.

Inverter Gates Selection Notes

Select this component when LSTTL-compatible inputs are required alongside CMOS performance characteristics. It serves as a functional equivalent to the LS32 pinout but offers improved noise immunity. Verify that the 4.5 V to 5.5 V supply voltage range matches the system power architecture before integration.

Inverter Gates Part Context

This part belongs to the 74HCT series of high-speed CMOS logic devices manufactured by onsemi. It implements the standard Quad 2-Input OR gate function defined in the JEDEC No. 7A standard. The device is designed to bridge legacy TTL logic requirements with modern low-power CMOS technologies.

Inverter Gates Replacement Considerations

The datasheet identifies the 74HCT32DR2G as a compatible alternative utilizing the SOIC-14 package instead of the TSSOP-14 form factor. Both variants share identical electrical characteristics and pinouts.

Inverter Gates FAQ

What is the maximum quiescent supply current for this device?

The maximum quiescent supply current is 20 µA at 25°C and 40 µA at 125°C when the supply voltage is 5.5 V.

How does the device handle unused inputs?

Unused inputs must always be tied to an appropriate logic voltage level, either GND or VCC, to ensure proper operation and prevent undefined states.
