Frequently Asked Questions - TPIC6C595N TEXAS INSTRUMENTS
What is the TPIC6C595N?
The TPIC6C595N is a high-voltage, high-current 8-bit power shift register from Texas Instruments. It accepts serial data and drives eight open-drain outputs.
What are the main specifications of the TPIC6C595N?
It operates with a VCC supply of 4.5 V to 5.5 V, supports output voltages up to 50 V, and provides 150 mA per channel.
How do I cascade multiple TPIC6C595N shift registers?
Connect the serial output of the first device to the SER IN pin of the next device, and drive all SRCLK and RCK pins in parallel.
What do the SRCLR and RCK pins do?
SRCLR clears the shift register when pulled low, while RCK transfers the shifted data to the storage register and output latches.
Can I use the TPIC6C595N to drive inductive loads such as relays?
Yes, but because the outputs are open-drain, place a flyback diode across the relay coil to clamp voltage spikes and protect the IC.
What is the maximum output current of the TPIC6C595N?
Each channel can sink 150 mA continuously. The total current is limited by package power dissipation and operating temperature.
What are typical applications for the TPIC6C595N?
It is commonly used for LED displays, relay drivers, stepper motors, solenoids, and any application needing digital output expansion.
How should I handle the TPIC6C595N to avoid damage?
It is an ESD-sensitive component. Use anti-static handling, grounded soldering stations, and avoid touching pins directly.
What is the difference between the TPIC6C595N and a standard 74HC595?
A standard 74HC595 has totem-pole outputs, while the TPIC6C595 has high-power open-drain outputs that can handle higher voltages and currents.
How do I choose LED series resistors when using the TPIC6C595N?
Use Ohm's law: R = (V_LOAD - V_LED) / I_LED. The output voltage is the external load supply, not the 5V logic supply.
