TPIC6C595D Power Logic 8-Bit Shift Register
The TPIC6C595D is a robust, high-voltage, high-current power logic 8-bit shift register designed and manufactured by Texas Instruments. This integrated circuit (IC) is specifically engineered to address the needs of systems that require relatively low data rates and high voltage digital serial to parallel conversion with output drive capabilities.
With its 8-bit serial-in, parallel-out shift register, the TPIC6C595D allows users to convert serial data into parallel output form, which is particularly useful in applications where there is a need to extend the number of outputs without increasing the number of microcontroller pins used. The device operates with a shift register and latch function, which enables the possibility of cascading multiple TPIC6C595Ds together, thereby increasing the number of controllable outputs without significant complexity.
The TPIC6C595D offers a range of features that make it suitable for driving a wide array of loads, including relays, solenoids, and other high-current or high-voltage devices. It is capable of sinking a high output current of up to 250 mA per channel and can withstand an output voltage of 33V on the drain pins. The power outputs are low-side, open-drain DMOS transistors with output clamp diodes for inductive transient suppression, providing protection and reliability in inductive switching applications.
Additional technical highlights of the TPIC6C595D include a 75 MHz clock frequency, which ensures smooth and fast data transfer, as well as an edge-triggered clock input, which simplifies the timing control. The IC also includes a clear function, which can reset the shift register, and a gated output enable function for better control of the output transition moments.
Available in a compact 16-pin SOIC package, the TPIC6C595D is ideal for a variety of industrial and consumer applications, including LED displays, digital signage, and other systems where power driving capability is critical. With its combination of power handling and ease of use, the TPIC6C595D is a practical solution for designers looking to implement reliable power logic control in their circuits.
