They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The output terminal ( CO/ZD ) goes to an active low state when the down count reaches zero. Since the TC74HC40102A is designed as a BCD counter, programming up to 99 counts is possible. The TC74HC40103A, with its 8-bit binary construction, can be set to provide up to 255 counts.
