The 74LV393-Q100 is a low–voltage Si-gate CMOS device and is pin and function compatible with 74HC393-Q100 and 74HCT393-Q100.
The 74LV393-Q100 is a dual 4-stage binary ripple counter. Each counter features a clock input (nCP), an overriding asynchronous master reset input (nMR) and 4 buffered parallel outputs (nQ0 to nQ3). The counter advances on the HIGH-to-LOW transition of nCP. A HIGH on nMR clears the counter stages and forces the outputs LOW, independent of the state of nCP.
This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.
