XD74LS90 XINLUDA

The XD74LS90 with Counters, Dividers DIP-14 RoHS is a 14-pin dual J-K flip-flop IC manufactured by XINLUDA.It is a two-stage dynamic counter that uses two independent 4-bit binary counters, with four internally synchronous distinct J-K flip-flops organized as one 8-bit binary counter or two synchronous 4-bit counters. The four J-K flip-flops consist of two J-K flip-flops configured as a bi-stable latch and two configured as QD edge-triggered flip-flops. This helps to effectively divide the clock frequency by two, four, six, or eight.This IC also has a synchronous reset input that sets the outputs of the flip-flops to low. It is capable of operating from a single 2.5V-6V supply and can also be operated from dual supplies.The XD74LS90 is RoHS compliant and comes in a DIP-14 package.
