SN75469N

Overview

The SN75469N is a high-voltage Darlington transistor array manufactured by Texas Instruments. It integrates seven independent NPN Darlington pairs within a single PDIP-16 package, designed for through-hole mounting. The device supports a maximum collector-emitter voltage of 100 V and a continuous DC collector current of 500 mA per channel. Each pair includes input resistors to simplify drive circuitry. The component operates within a temperature range of 0°C to +70°C and features a maximum collector cutoff current of 500 µA.

Feature Summary

Integrates seven independent NPN Darlington pairs with built-in input resistors
Supports high-voltage switching applications up to 100 V collector-emitter rating
Provides high current gain capability suitable for direct interface with logic circuits

Applications

Stepper motor driving via peripheral drivers
High-voltage relay driver circuits
Lamp and lighting control systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the procurement source provides valid traceability documentation. Confirm that the component meets required environmental standards such as RoHS compliance before integration into final assemblies.

Selection Notes

Select this component when designing circuits requiring multiple high-voltage switching channels in a compact through-hole footprint. Consider the 500 mA per-channel limit and total power dissipation constraints relative to the PCB thermal design. Verify that the input resistor values align with the driving logic voltage levels to ensure proper saturation.

Part Context

This part belongs to the SN75468/SN75469 series of high-voltage Darlington arrays from Texas Instruments. It serves as a discrete solution for driving inductive loads where integrated MOSFET drivers may lack sufficient voltage ratings. The PDIP-16 package offers a standard form factor for legacy and industrial board designs.
