The 74LVC594AD.112 part from Nexperia is an 8 bit bidirectional universal shift register with parallel I/O and a pair of bus terminals (A and B). It has 5-V tolerant I/O and is designed for low-voltage, low-power applications. It supports 8 bits of parallel data loading and shifting, synchronous or asynchronous. It features an internal control register which can control the shift and storage direction, as well as providing a dedicated clock input. It also features an asynchronous clear and preset input. The 74LVC594AD.112 is pin- and register compatible with the 74HC594A, 74HCT594A, and 74HC594, and is suitable for applications such as PLCs, industrial and appliance products, security systems, building automation systems, digital power converters, automated test systems, and automotive solutions.
