Overview
The TPIC6C596PWR device, produced by Texas Instruments, is a monolithic, medium-voltage, low-current, 8-bit shift register. It is designed for use in systems that require relatively moderate load power, such as driving LEDs, relays, solenoids, and other low-current or medium-voltage loads. The device features a built-in voltage clamp on the outputs for inductive transient protection and is particularly well-suited as an interface between a microcontroller and various loads.

Q & A
- What is the operating temperature range of the TPIC6C596PWR?
The operating temperature range is -40°C to 125°C. - What is the supply voltage range for the TPIC6C596PWR?
The supply voltage range is 4.5 V to 5.5 V. - What type of outputs does the TPIC6C596PWR have?
The device has open-drain DMOS transistor outputs. - What is the maximum current limit per output at TC = 25°C?
The maximum current limit is 250 mA per output at TC = 25°C. - Does the TPIC6C596PWR have ESD protection?
Yes, it provides up to 2500 V of ESD protection. - How does the device handle cascaded applications?
The serial output (SER OUT) is clocked out on the falling edge of SRCK to provide additional hold time for cascaded applications. - What is the propagation delay of the TPIC6C596PWR?
The propagation delay is 80 ns. - Is the TPIC6C596PWR RoHS compliant?
Yes, it is RoHS compliant. - How are the registers cleared in the TPIC6C596PWR?
All registers are cleared with a single input (CLR) set to low. - What is the typical use of the output enable (G) pin?
Holding the output enable (G) low makes data from the storage register transparent to the output buffers, and it can also be used for global PWM dimming.
