Overview
The TPIC6C596DRDN 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 an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register, enabling efficient data transfer and control over multiple outputs.

Q & A
- What is the primary function of the TPIC6C596DRDN device?
The primary function is to act as an 8-bit serial-in, parallel-out shift register designed to drive moderate load power devices like LEDs, relays, and solenoids. - What is the operating temperature range of the TPIC6C596DRDN?
The operating temperature range is from -40°C to 125°C. - What is the maximum output voltage rating of the TPIC6C596DRDN?
The maximum output voltage rating is 33 V. - What is the continuous sink-current capability of each output?
Each output has a continuous sink-current capability of 100 mA. - Does the TPIC6C596DRDN 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, improving performance in systems with skewed clock signals or electromagnetic interference. - What is the purpose of the output enable (G) pin?
The output enable (G) pin, when held low, makes data from the storage register transparent to the output buffers, and when held high, it holds all data in the output buffers low and turns off all drain outputs. - Can the TPIC6C596DRDN be used in automotive applications?
Yes, it is particularly well-suited for automotive applications, such as in automotive cluster drivers. - How does the device protect against inductive transients?
The device contains a built-in voltage clamp on the outputs for inductive transient protection. - What is the maximum current limit at 25°C for each output?
The maximum current limit at 25°C for each output is 250 mA.
