74HCT4075N,652

Overview

The NXP USA Inc. 74HCT4075N,652 is a triple 3-input OR gate belonging to 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-level input compatibility and includes internal clamp diodes on all inputs. It provides three independent OR gates with standard output capability in a 14-lead SO plastic small outline package (SOT108-1).

Feature Summary

• Provides three independent 3-input OR logic functions.
• Features TTL-compatible input levels for direct interfacing with Transistor-Transistor Logic systems.
• Includes input clamp diodes allowing current limiting resistors for voltages exceeding VCC.
• Offers ESD protection exceeding 2000 V under Human Body Model testing.

Applications

• Logic circuit design requiring multiple OR operations.
• Signal routing and selection networks.
• General-purpose digital logic applications.

Procurement Notes

Verify that the ordering suffix matches the required package type and temperature grade. Confirm the specific revision level against the manufacturer's latest documentation to ensure compliance with current JEDEC standards and product specifications before finalizing procurement orders.

Selection Notes

Select this component when TTL-level input thresholds are required alongside CMOS performance characteristics. Ensure the application environment remains within the specified operating temperature limits. Verify that the load capacitance requirements align with the dynamic performance specifications provided in the datasheet.

Part Context

This part belongs to the 74HCT series of high-speed silicon-gate CMOS devices. It maintains pin compatibility with the legacy 4000B series while offering improved switching speeds. The device is manufactured by Nexperia B.V., which acquired the semiconductor assets previously associated with NXP Semiconductors.

Replacement Considerations

The 74HC4075 serves as a functional alternative but requires CMOS-level input signals rather than TTL levels. Cross-reference the package dimensions and lead pitch to ensure mechanical compatibility during replacement or redesign processes.
