Overview
The TPIC6C596DRG4, 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 driving relatively moderate load power, such as 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 and offers enhanced cascading capabilities for multiple stages, making it suitable for various applications including automotive and instrumentation clusters.

The device operates from an input voltage supply range of 4.5 V to 5.5 V.
- What is the maximum current limit per channel?
The maximum current limit per channel is 250 mA at TC = 25°C.
- How does the device protect against inductive transients?
The device includes built-in voltage clamps on the outputs for inductive transient protection.
- What is the ESD protection rating of the TPIC6C596DRG4?
The device provides up to 2500 V of ESD protection.
- How does the serial output (SER OUT) enhance cascading performance?
The serial output (SER OUT) is clocked on the falling edge of SRCK to provide additional hold time for cascaded applications.
- What are the package types available for the TPIC6C596DRG4?
The device is available in SOIC (16), PDIP (16), and TSSOP (16) packages.
- What is the operating case temperature range of the TPIC6C596DRG4?
The device operates over a case temperature range of -40°C to 125°C.
- How do you clear all registers in the device?
A logical low on the CLR (Clear) pin clears all registers in the device.
- What is the function of the output enable (G) pin?
Holding the output enable (G) pin low makes data from the storage register transparent to the output buffers, while holding it high keeps all data in the output buffers low and all drain outputs off.
