8Bit synchronous binary down counter
GENERAL DESCRIPTION
The 74HC/HCT40103 are high-speed Si-gate CMOS devices and are pin compatible with the “40103” of the “4000B” series. They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT40103 consist each of an 8-bit synchronous down counter with a single output which is active when the internal count is zero. The “40103” contains a single 8-bit binary counter and has control inputs for enabling or disabling the clock CP, for clearing the counter to its maximum count, and for presetting the counter either synchronously or asynchronously. All control inputs and the terminal count output TC are active-LOW logic.
