Dual 4-stage Binary Ripple Counter High-performance Silicon-gate Cmos

The KK74HC393A is identical in pinout to the LS/ALS393. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This device consists of two independent 4-bit binary ripple Counters with parallel outputs from each Counter stage. A256 Counter CAN be obtained by cascading the two binary Counters Internal Flip-Flops are triggered by high-to-low transitions of the Clock input. Reset for the Counters is asynchronous and active-high. State changes of the Q outputs do not occur simultaneously because of internal ripple delays. Therefore, decoded output signals are subject to decoding spikes and should not be used as Clocks or as strobes except when gated with the Clock of the KK74HC393A. Outputs Directly Interface to CMOS, NMOS, and TTL Operating Voltage Range: 2.0 to 6.0 V Low Input Current: 1.0 A High Noise Immunity Characteristic of CMOS Devices By Kodenshi Korea Corp.
