series introduction
# TPIC6B259 Product Series Introduction
## Overview
The TPIC6B259 is a highly versatile and reliable product series that belongs to the category of high - current, 8 - bit shift registers with 3 - state outputs. This series is designed to meet the demanding requirements of various industrial, automotive, and consumer electronics applications. It offers a cost - effective solution for driving high - current loads while providing efficient control and flexibility.
## Key Features
### High - Current Drive Capability
One of the most significant features of the TPIC6B259 series is its ability to drive high - current loads. Each output can sink up to 150 mA of continuous current and can handle peak currents of up to 500 mA. This makes it suitable for directly driving a wide range of devices such as LEDs, relays, solenoids, and small motors. For example, in automotive lighting applications, it can easily drive the high - intensity LEDs used in brake lights or turn signals.
### 8 - Bit Shift Register Functionality
The TPIC6B259 incorporates an 8 - bit shift register, which allows for serial data input. This feature simplifies the interface with microcontrollers or other control devices. Data can be shifted in one bit at a time, and once all 8 bits are loaded, they can be latched to the outputs simultaneously. This serial - to - parallel conversion is extremely useful in applications where the number of available output pins on a microcontroller is limited. For instance, in a large - scale LED display system, the TPIC6B259 can be used to reduce the number of control lines required from the microcontroller.
### 3 - State Outputs
The 3 - state outputs of the TPIC6B259 provide additional flexibility. In the high - impedance state, the outputs are effectively disconnected from the load. This feature is useful in bus - based systems where multiple devices may share the same output lines. By putting the outputs of the TPIC6B259 in the high - impedance state, other devices can use the same lines without interference. For example, in a multi - module industrial control system, the 3 - state outputs allow for easy daisy - chaining of multiple TPIC6B259 devices.
### Schmitt - Trigger Inputs
The inputs of the TPIC6B259 are equipped with Schmitt - trigger circuits. Schmitt - trigger inputs have hysteresis, which means they are less sensitive to noise and voltage fluctuations. This makes the device more reliable in noisy environments, such as industrial settings where electrical interference is common. It ensures that the input signals are accurately detected, reducing the likelihood of false triggering.
### Wide Operating Voltage Range
The TPIC6B259 series operates over a wide voltage range, typically from 4.5 V to 18 V. This wide voltage range allows it to be used in a variety of power supply configurations. It can be easily integrated into systems with different power requirements, whether it is a low - voltage battery - powered device or a higher - voltage industrial control system.
## Applications
### Automotive Electronics
In the automotive industry, the TPIC6B259 is widely used for various lighting and control applications. It can drive the interior and exterior lighting systems, including dashboard lights, taillights, and turn signals. Its high - current drive capability and reliability make it suitable for the harsh automotive environment, where it must withstand temperature variations, vibrations, and electrical noise. Additionally, it can be used to control small motors in automotive accessories such as power windows or seat adjusters.
### Industrial Automation
In industrial automation, the TPIC6B259 plays a crucial role in controlling relays, solenoids, and other high - current actuators. It can be used
