Logic Symbol 3 Description The TPIC6B595 device is a monolithic, high-voltage, medium-current power 8-bit shift register designed for use in systems that require relatively high load power. The device contains a built-in voltage clamp on the outputs for inductive transient protection. Power driver applications include relays, solenoids, and other medium current or high-voltage loads. This device contains an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. Data transfers through the shift and storage registers on the rising edge of the shift-register clock (SRCK) and the register clock (RCK), respectively. The storage register transfers data to the output buffer when shift-register clear ( SRCLR) is high. Write data and read data are valid only when RCK is low. When SRCLR is low, the input shift register is cleared. When output enable ( G) is held high, all data in the output buffers is held low and all drain outputs are off. When G is held low, data from the storage register is transparent to the output buffers. When data in the output buffers is low, the DMOS-transistor outputs are off. When data is high, the DMOS transistor outputs have sink-current capability. The serial output (SER OUT) allows for cascading of the data from the shift register to additional devices. Outputs are low-side, open-drain DMOS transistors with output ratings of 50V and 150m A...
