Philips 8bit serialinserial or parallelout shift register with output latches. July 20 diodes incorporated preliminary 74hct595 pin descriptions pin number pin name description. At the raising edge of the latch signal, the data shows up on the output pins d0d7, where d7 has the least significant bit the blue wire is going from the serial out pin pin 9 of the first shift register to the serial data input pin 14 of the second register.
As the data gets shifted in it is saved in an internal memory register. You can get around this by controlling the mr and oe pins from your arduino board too. Download the free library loader to convert this file for your ecad tool. The data gets shifted into the device on each raising edge of the clock signal. Hello, you need to check the schematics of your board if this is possible at all. So i can use several times the shiftbyte method if i have chained shift registers.
