A LOW signal DESCRIPTION on LOAD overrides counting and allows The 74ACT163 is an advanced high-speed CMOS information on Parallel Data inputs to be loaded SYNCRONOUS PRESETTABLE COUNTER into the flip-flop on the next rising edge of CLOCK. fabricated with sub-micron silicon gate and With LOAD and CLEAR HIGH, PE and TE permit double-layer metal wiring C2MOS tecnology. It is a counting when both are HIGH. Conversely, a 4 bit binary counter with Synchronous Clear. LOW signal on either PE and TE inhibits counting. The circuit have four fundamental modes of The device is designed to interface directly High operation, in order of preference: synchronous
