Working Principles

The TPIC6B596DW is a shift register and latch IC that allows serial data input to be converted into parallel outputs. It operates by shifting the input data bit-by-bit into the shift register using the shift register clock (SRCLK) input. The register clock (RCLK) input latches the shifted data into the storage latches, which can then be held until new data is received.

The output enable (OE) input controls whether the outputs are enabled or disabled. When OE is high, the outputs are enabled, allowing the stored data to appear at the parallel output channels (QA-QH). Conversely, when OE is low, the outputs are disabled, and the outputs remain in their previous state.

The shift register clear (SRCLR) input clears the shift register to a known state, resetting all the outputs to a low logic level. This feature ensures a predictable starting point for the shift register operation.

Detailed Application Field Plans

The TPIC6B596DW is commonly used in various applications where efficient control of high-power loads is required. Some typical application fields include:
