74HC40103 datasheet



The 74HC40103 is a high-speed Si-gate CMOS device and are pin compatible with the 40103 of the 4000B series. The 74HC40103 is specified in compliance with JEDEC standard no. 7A.

The device consists of an 8-bit synchronous down counter with a single output which is active when the internal count is zero. The 74HCT40103 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.



1. Cascadable

2. Synchronous or asynchronous preset

3. Output capability: standard

4. ICC category: MSI
