Product Introduction

Overview

The SN75468NSR, produced by Texas Instruments, is a high-voltage, high-current Darlington transistor array. This device consists of seven NPN Darlington pairs, each capable of handling up to 500 mA of collector current. It is designed to operate with various types of logic, including TTL and CMOS, and features high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The SN75468NSR is particularly useful in applications requiring the drive of high voltage and/or current peripherals from microcontrollers or logic devices that cannot tolerate these conditions.

Q & A

  1. What is the maximum collector current per output of the SN75468NSR?

    The maximum collector current per output is 500 mA.

  2. What is the maximum high-voltage output of the SN75468NSR?

    The maximum high-voltage output is 100 V.

  3. Is the SN75468NSR compatible with TTL and CMOS logic?
  4. What is the purpose of the output clamp diodes in the SN75468NSR?

    The output clamp diodes are used to suppress the kick-back voltage from inductive loads.

  5. Can the Darlington pairs in the SN75468NSR be paralleled for higher current capability?
  6. What is the operating temperature range of the SN75468NSR?

    The operating temperature range is from -40°C to 105°C.

  7. What types of loads can the SN75468NSR drive?

    The SN75468NSR can drive inductive loads, resistive loads, relays, solenoids, lamps, and display devices.

  8. How does the SN75468NSR handle power dissipation?

    The SN75468NSR's power dissipation must be managed to keep the junction temperature below 125°C. This involves calculating the on-chip power dissipation based on the number of active channels and the load current.

  9. What package types are available for the SN75468NSR?

    The SN75468NSR is available in SOP (NS) package.

  10. What are some common applications of the SN75468NSR?
