Compatible with the 74HC595 standard, it features separate shift and storage clocks, direct reset, and output enable control. Operating from 2V to 6V with 55 MHz shift frequency, it is ideal for I\/O expansion, LED driving, and serial-to-parallel data conversion in microcontroller systems.","working_principle":"The AIP74HC595D consists of an 8-bit shift register and an 8-bit storage register, each with independent clock inputs. Serial data is clocked into the shift register on the rising edge of SHCP. The rising edge of STCP transfers the shift register contents to the storage register, which drives the parallel outputs. The MR pin asynchronously resets the shift register, while OE controls the 3-state output enable. The serial output Q7S allows cascading multiple devices for more than 8 bits of I\/O expansion.","pin_description":"\n
