# CD40103BE (Component)

## Description

Counter IC Binary Counter 1 Element 8 Bit Positive Edge 16\-PDIP

CMOS 8\-bit presettable synchronous binary down counter that performs binary countdown operations with synchronous or asynchronous preset capability and an active\-low zero\-detect/carry output for cascading\. It operates from a 3 V to 18 V supply, supports typical clock frequencies up to 3\.6 MHz at VDD = 10 V, and includes asynchronous clear, clock enable, and cascadable operation for programmable counting applications\.
