Texas Instruments Bipolar Transistor Array NPN 50V 500mA TSSOP
Texas Instruments NPN Darlington transistor array with seven channels, 500mA per output and 50V rating in a surface-mount TSSOP package.
Texas Instruments Bipolar Transistor Array NPN 50V 500mA TSSOP is a high-voltage, high-current surface-mount driver array supplied in a compact TSSOP package.
Overview
This array contains seven open-collector NPN Darlington pairs with common emitters, providing power amplification for demanding switching tasks. Each output channel handles up to 500mA and withstands voltages up to 50V. For applications requiring higher current, the outputs can be safely paralleled. The supply voltage range of 6V to 15V offers flexibility across different power supply environments.
Key Features
- Integrated suppression diodes for inductive loads, built directly onto the chip
- Input pins placed opposite the output pins to simplify PCB layout and routing
- Compatible with TTL, CMOS, PMOS and DTL logic families
- Maximum operating temperature of 105°C
- Weight of 0.104 g
Applications
This component is suited to driving loads where reliability is critical. Typical uses include controlling relays and solenoids, driving stepper motors and DC brushed motors, powering indicator lamps and display drivers including LEDs and gas discharge displays, and acting as a line driver or logic buffer between low-power logic and higher-power peripherals.
The compact TSSOP surface-mount package is suited to designs with limited board space.
