74HCT2G32DP,125

Overview

The Nexperia 74HCT2G32DP,125 is a dual 2-input OR gate in the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL input levels and CMOS low power dissipation. Propagation delay is typically 13 ns at 4.5 V with a maximum of 36 ns across the operating temperature range. Output drive capability reaches ±5.2 mA. It is housed in an SOT505-2 (TSSOP8) package.

Feature Summary

• Provides two independent 2-input OR logic functions in a compact surface-mount package.
• Features clamp diodes on inputs to allow interfacing with voltages exceeding VCC using current limiting resistors.
• Offers high noise immunity and balanced propagation delays for reliable signal processing.
• Includes robust ESD protection compliant with JEDEC standards for human body model and charged device model.

Applications

• Signal routing in mixed-voltage digital systems
• Logic level translation between TTL and CMOS domains
• General-purpose boolean logic operations in embedded controllers

Procurement Notes

Verify the specific ordering suffix matches the required package variant and temperature grade. Confirm RoHS compliance status and REACH registration details against current regulatory requirements. Ensure the component source is an authorized distributor to guarantee authenticity and traceability. Check for any recent product change notices that may affect marking or assembly specifications.

Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS output characteristics. The wide operating temperature range makes it suitable for industrial environments. Consider the TSSOP8 package dimensions for PCB layout constraints. Verify that the supply voltage remains within the specified 4.5 V to 5.5 V range to ensure proper logic threshold operation.

Part Context

This part belongs to the Nexperia 74HCT series of high-speed Si-gate CMOS devices. It is designed for applications requiring compatibility with standard TTL logic levels while offering improved speed and lower power consumption compared to older LS families. The dual configuration allows multiple logic functions in a single small outline package.

Replacement Considerations

Direct replacements include other 74HCT2G32 variants from different manufacturers that meet the same electrical specifications and pinout configuration. Ensure any substitute maintains the same TSSOP8 package footprint and thermal characteristics. Verify that the replacement also supports the required -40 °C to +125 °C operating temperature range.
