74HC393N

The 74HC393N is a 4-stage dual Binary Ripple 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\. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.

• Two 4-bit Binary counters with individual clock
• Two Master resets to clear each 4-bit counter individually
• CMOS Input levels
• Complies with JEDEC standard No. 7A
