Overview
The ULN2003APG,CN is a high-voltage, high-current Darlington transistor array manufactured by Toshiba Semiconductor and Storage. It integrates seven independent NPN Darlington pairs, each equipped with a common emitter connection and internal clamp diodes for inductive load protection. The component features series input resistors optimized for direct interfacing with 5V TTL or CMOS logic families. Key electrical parameters include a maximum continuous collector current of 500 mA per channel and an output voltage withstand capability of at least 50 V in the OFF state. The device is housed in a 16-pin DIP package and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates seven independent NPN Darlington pairs with common emitter configuration
- Includes integral clamp diodes on all outputs for inductive load flyback suppression
- Features built-in series input resistors compatible with standard 5V logic levels
Applications
- Relay driver circuits
- Solenoid and magnetic print hammer control
- Stepping motor interface modules
- Multiplexed LED and incandescent display drivers
Procurement Notes
Verify the specific suffix 'CN' against official Toshiba documentation to confirm regional compliance or marking variations. Ensure the procurement source provides valid RoHS compliance data consistent with the 'PG' designation. Confirm that the supplier offers genuine Toshiba Semiconductor and Storage products rather than third-party alternatives.
Selection Notes
Select this component when driving multiple inductive loads from low-power logic sources without external buffering. The integrated resistors simplify design for 5V systems. For applications requiring higher voltage ratings (95V), consider the ULN2023A variant. Verify thermal management requirements if operating near the maximum power dissipation limits.
Part Context
This part belongs to the ULN20xxA/L series of Darlington arrays designed for interfacing low-level logic with peripheral power loads. The 'APG' suffix typically denotes a through-hole DIP-16 package with lead-free construction. The 'CN' suffix likely indicates specific manufacturing origin or packaging details defined by Toshiba.
Replacement Considerations
The ULN2003A is the standard equivalent part number. Other variants like ULN2003AFWG offer surface-mount solutions with identical electrical characteristics. Ensure pinout compatibility when substituting.
