What does the latch pin do?

What does the latch pin do?

The basic principle of the locking device is that the latch pin blocks the circuit breaker from operating the closing pawl of the breaker mechanism, so that the circuit breaker is always maintained at the opening position and cannot be closed. The isolation latch can be operated remotely or locally.

What is an 8-bit shift register?

The SN74HC595N is a simple 8-bit shift register IC. Simply put, this shift register is a device that allows additional inputs or outputs to be added to a microcontroller by converting data between parallel and serial formats. Essentially it takes 8 bits from the serial input and then outputs them to 8 pins.

Where is the RESET pin on a 74hc595 shift register?

Applying a low signal at pin 10 will reset the shift register portion only. This is the clock input pin of a 74hc595 shift register. A data is shifted from the serial input pin to the 8-bit shift register on every positive transition of the clock signal applied at this pin.

How many output pins does the 74hc595 have?

The 74hc595 has 8 output pins out of which 7 are these pins. They can be controlled serially Resets all outputs as low. Must be held high for normal operation This is the clock pin to which the clock signal has to be provided from MCU/MPU The Latch pin is used to update the data to the output pins. It is active high

How does Arduino 74hc595 shift register interfacing work?

74HC595 Shift Register Interfacing with Arduino 74HC595 IC is a 16-pin shift register IC consisting of a D-type latch along with a shift register inside the chip. It receives serial input data and then sends out this data through parallel pins. In addition to parallel outputs, it also provides a serial output.

Where to use 74hc595 IC, serial in parallel?

Where to Use 74HC595 IC The 74HC595 is an 8-bit Serial In – Parallel Out Shift Register, i.e. it can receive (input) data serially and control 8 output pins in parallel. This comes in very handy where do not have enough GPIO pins on our MCU/MPU to control the required number of outputs.
