BCD Counter Circuit using the 74LS90 Decade Counter
The 74LS90 integrated circuit is basically a MOD-10 decade counter that produces a BCD output code. The 74LS90 consists of four master-slave JK flip-flops internally connected to provide a MOD-2 (count-to-2) counter and a MOD-5 (count-to-5) counter.
74LS90 Decade Counter Pinout and Examples - Microcontrollers …
74LS90 Decade Counter Pinout and Examples. 74LS90 is a binary decade counter without an automatic reset feature. There multiple kinds of counters which we can use in devices for binary or decimal counting. We discussed a counter 74LS93 IC, which is based on a T-type flip flop. In case of attaching the toggle, flip flops in series we can ...

Building a BCD Counter Circuit with the 74LS90 Decade Counter
2023年10月24日 · This article delves into what a BCD counter is, how the 74LS90 Decade Counter operates, and how to build a BCD counter circuit utilizing this integrated circuit (IC).
The SN54/74LS90, SN54/74LS92 and SN54/74LS93 are high-speed 4-bit ripple type counters partitioned into two sections. Each counter has a divide-by-two section and either a divide-by-five (LS90), divide-by-six (LS92) or divide-by-eight (LS93) section which are triggered by a HIGH-to-LOW transition on the clock inputs.

74LS90 Decade and Binary Counters . Each of these monolithic counters contains four masterslave flip-flops and additional gating to provide a divide-bytwo counter and a three-stage binary counter for which the count cycle length is divide-by-five for the DM74LS90.
The SN54/74LS90, SN54/74LS92 and SN54/74LS93 are high-speed 4-bit ripple type counters partitioned into two sections. Each counter has a di-vide-by-two section and either a divide-by-five (LS90), divide-by-six (LS92) or divide-by-eight (LS93) section which are triggered by a HIGH-to-LOW transi-tion on the clock inputs.
