SN74HCT32APWLE

Inverter Gates Overview

The SN74HCT32APWLE is a quadruple 2-input positive-OR gate manufactured by Texas Instruments. It belongs to the HCT logic family, designed for CMOS operation with TTL-compatible inputs. The device features four independent OR gates within a single package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -40°C to 85°C. The component is housed in a 14-pin TSSOP (Thin Shrink Small Outline Package) with a lead pitch of 0.65 mm.

Inverter Gates Feature Summary

• Provides four independent 2-input OR logic functions
• Ensures compatibility with standard TTL logic levels through HCT input thresholds
• Utilizes low-power CMOS technology for efficient power consumption
• Offers compact surface-mount packaging suitable for high-density board layouts

Inverter Gates Applications

• Digital signal processing circuits requiring logical OR operations
• Data routing and selection logic in embedded systems
• Control logic interfaces between microcontrollers and peripheral devices
• General-purpose digital logic implementation in consumer electronics

Inverter Gates Procurement Notes

Verify the complete part number including the APWLE suffix to confirm the specific TSSOP-14 package variant and tape-and-reel configuration. Ensure the procurement source provides documentation confirming compliance with RoHS directives and lead-free manufacturing standards. Cross-reference the manufacturer's latest datasheet to validate pinout assignments and electrical characteristics against current design requirements before finalizing orders.

Inverter Gates Selection Notes

Select this component when designing systems that require interface compatibility between 5V CMOS logic and legacy TTL components. The HCT series is appropriate for applications needing faster switching speeds than standard HC series while maintaining lower power consumption than LS series. Consider the TSSOP package dimensions if space constraints are critical, ensuring adequate thermal management for the specified operating temperature range.

Inverter Gates Part Context

This component is part of the broader 74HCT logic family, which bridges the gap between older TTL technologies and modern CMOS implementations. The '32' designation specifically identifies the OR gate function within the industry-standard numbering system. Texas Instruments produces this series to support designs transitioning from bipolar to CMOS architectures, offering improved noise immunity and reduced power dissipation compared to earlier generations.

Inverter Gates Replacement Considerations

Compatible substitutes include SN74HC32 variants for higher speed applications or SN74ACT32 for advanced performance. Verify pin-to-pin compatibility and ensure voltage level matching between the replacement and original circuit requirements.
