TPIC6B595DWRG4 Power Logic 8-Bit Shift Register by Texas Instruments

The TPIC6B595DWRG4 is a high-performance, monolithic power logic 8-bit shift register designed and manufactured by Texas Instruments. This integrated circuit is engineered to provide an optimal solution for applications requiring high-voltage, high-current control and interfacing with microprocessor systems. It is particularly well-suited for driving a wide range of loads, including solenoids, relays, DC motors, LED displays, and incandescent lamps.

Constructed with an 8-bit serial-in, parallel-out shift register and an 8-bit D-type storage register, this device allows for serial data input and parallel data output. The shift register and storage register have separate clocks. Data is shifted on the positive-going transitions of the shift register clock (SRCK), and the data in the storage register is transferred to the output buffer on a positive-going transition of the register clock (RCK).

Each of the eight output pins is equipped with a Darlington transistor pair with a DMOS output structure. These output drivers feature a high-voltage, high-current capability with a typical output of 50V and 150mA continuous current. The TPIC6B595DWRG4 also includes a built-in clamp diode for inductive load transient suppression, making it an ideal choice for controlling inductive loads.

Another key feature of the TPIC6B595DWRG4 is its low power consumption. The device operates with a supply voltage range of 4.5V to 5.5V, ensuring compatibility with standard TTL logic levels. The device's inputs are designed to withstand –20-V pulses for enhanced robustness.

For ease of implementation, the TPIC6B595DWRG4 comes in a wide-body SOIC (DWR) package, which provides improved thermal performance and is suitable for surface-mount technology (SMT). This package also allows for efficient PCB space utilization, making it a space-saving option for compact electronic designs.

Whether for industrial controls, office automation, consumer electronics, or automotive applications, the TPIC6B595DWRG4 offers a reliable and efficient solution for serial-to-parallel data conversion and high-power output driving capabilities.
