Description :

description/ordering information
The CD74HC40103 is manufactured with high-speed silicon-gate technology and consists of an 8-stage synchronous down counter with a single output, which is active when the internal count is zero. The device contains a single 8-bit binary counter. Each device has control inputs for enabling or disabling the clock, for clearing the counter to its maximum count, and for presetting the counter either synchronously or asynchronously. All control inputs and the terminal count (TC) output are active-low logic. In normal operation, the counter is decremented by one count on each positive transition of the clock (CP) output. Counting is inhibited when the terminal enable (TE) input is high. TCgoes low when the count reaches zero, if TEis low, and remains low for one full clock period.
