Introduction

The TPIC6A596DWR is a 10-bit shift register/digital logic integrated circuit (IC). It is part of the Texas Instruments Logic product portfolio and is intended for applications such as LCD/LED display driver, string lighting, communication system, device address decoding, and data transfer. This device is a reprogrammable device that includes a logic window that allows the user to program it functions on the fly. It offers good power efficiency and reduces the burden on the power supply circuitry.

Logic - Shift Registers

The TPIC6A596DWR assists in the efficient conversion of parallel data to serial output or serial input to parallel output. It also can perform bi-directional data transfer which makes it an ideal shift register for many applications. Its parallel shift register stores binary data in 10 flip-flops that can be accessed simultaneously by a common line. It comes with an asynchronous or synchronous capability by providing two clock inputs, allowing multiplexing or serializing of two digital signals. Its low-voltage operation, wide supply voltage range and digital operation provide reduced power consumption over conventional logic circuits.

Pinout Description

The TPIC6A596DWR has a total of 16 pins. The following table gives a brief description of each pin:

• Pins 1-7 – Seven data inputs
• Pin 8 – Master/Slave clock input for serial data input and output
• Pin 9 – Clock input for parallel data input, parallel data output, and direct control of the output driver
• Pin 10 – Output enable, active low
• Pins 11-13 – Three select options provided on the device
• Pin 14 – Serial data output
• Pins 15-16 – These are the power supply pins

Application Field

The TPIC6A596DWR is suitable for use in a wide variety of design applications. It is especially useful in any applications requiring the storage and retrieval of binary data, such as video displays, automotive dashboard displays, gaming systems, and office automation applications. Further applications include:

• Data Bus
• Codecs
• Stereo Systems
• Security Systems
• LED and LCD displays
• Communication System
• Data Logging

Working Principle

The TPIC6A596DWR is a synchronous 10-bit shift register with 3 selectable options that enables simultaneous shifting of two different digital signals. The device utilizes a Master/Slave clock input (Pin 8) and a Clock input (Pin 9) to control the data movement of the two signals. The device also has an output enable pin (Pin 10) that is active low and is used to control the outputs from the device. Parallel data is transferred in and out of the device through the seven data input pins (Pins 1-7). The Shift Register enables the serial input and parallel output of data by controlling the Clock input and the Master/Slave Clock input.The device can be configured in three modes: modes 1, 2, and 3. Mode 1 enables the device to perform parallel-to-serial data input in response to the Master/Slave clock transition. Mode 2 enables it to perform serially-to-parallel data output in response to the Master/Slave clock transition. Mode 3 enables it to perform serial-to-serial data transfer in response to the Master/Slave clock transition.

Conclusion

The TPIC6A596DWR is a versatile 10-bit shift register/digital logic IC designed for multiple applications. It offers fast performance, low-voltage operation, wide supply voltage range, and low-power consumption. Its synchronous capability provides the flexibility to perform parallel-to-serial, serial-to-parallel, and serial-to-serial data transfer. It is suitable for applications such as LED/LCD display driver, communication system, device address decoding, and data transfer.
