Overview
The TPIC6C596DRQ1, produced by Texas Instruments, is a monolithic, medium-voltage, low-current 8-bit shift register. This device 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. It features an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register, providing efficient data transfer and control. The device includes built-in voltage clamps on the outputs for inductive transient protection, enhancing its reliability in various applications.

Q & A
- What is the operating voltage range of the TPIC6C596DRQ1?
The TPIC6C596DRQ1 operates from an input voltage supply range of 4.5 V to 5.5 V.
- What is the maximum continuous drain current per output?
The maximum continuous drain current per output is 100 mA.
- What is the ESD protection rating of the TPIC6C596DRQ1?
The device provides up to 2500 V of ESD protection.
- How does the output enable (G) pin function?
Holding the output enable (G) high holds all data in the output buffers low, and all drain outputs are off. Holding G low makes data from the storage register transparent to the output buffers.
- What is the purpose of the built-in voltage clamp on the outputs?
The built-in voltage clamp provides inductive transient protection.
- Can the TPIC6C596DRQ1 be used in cascaded applications?
- What is the maximum serial clock frequency for the TPIC6C596DRQ1?
The maximum serial clock frequency is 10 MHz.
- How does the clear register function work?
A logical low on the CLR pin clears all registers in the device.
- What is the operating case temperature range of the TPIC6C596DRQ1?
The device operates over a case temperature range of –40°C to 125°C.
- What types of loads can the TPIC6C596DRQ1 drive?
The device can drive resistive and inductive loads, including LEDs, relays, and solenoids.
