What is the difference between 7490 and 7493?
Explanation: The difference between a 7490 and a 7493 is that 7490 is a MOD-10, 7493 is a MOD-16 counter. Thus, 7490 traverses 10 states and 7493 traverses 16 states. 2. Explanation: IC 7493 is a 4-bit binary ripple counter.
Which IC is called ripple or decade counter?
A binary coded decimal (BCD) is a serial digital counter that counts ten digits . And it resets for every new clock input. As it can go through 10 unique combinations of output, it is also called as “Decade counter”. This ripple counter can count up to 16 i.e. 24. …
How BCD counter is also called?
Explanation: BCD counter is also known as decade counter because both have the same number of stages and both count from 0 to 9.
What is 74LS93?
74LS93 or SN74LS93 is a 4-bit binary counter. Counters have a major role in every electronics device. The output of the counters can be used in multiple devices as pulse counting or for generating interrupts, etc. Counters come up in two form Asynchronous and Synchronous counters.
What are BCD counters?
A BCD (Binary Coded Decimal) counter also termed as decade counter is a series type of digital counter which is designed to count ten digits. It performs the operation of resetting automatically when there is a new clock input signal.
How does the 74LS93 work?
The 74LS93 is a up-counter built using four JK flip-flops. The CP1 and Q0 forms a mod-2 counter using a single flip-flop and the CP0 with Q1, Q2 and Q3 with three flip-flops forms the mod-8 counter. The IC is commonly used by combining mod-2 and mod-8 to form a mod-16 up-counter.
What kind of counter does 74ls90 IC use?
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 generate 2
What kind of BCD code does 74ls90 generate?
74LS90 is basically a MOD-10 decade counter that generate a BCD output code. It consists of four master-slave JK flip-flop, which are internally connected to provide MOD-2 (count to 2) counter and MOD-5 counter. 74LS90 also have an independent toggle JK flip-flop by CLKA and other three are driven by the CLKB.
What can a 74ls93 4 bit binary counter do?
74LS93 or SN74LS93 is a 4-bit binary counter. Counters have a major role in every electronics device. The output of the counters can be used in multiple devices as pulse counting or for generating interrupts, etc. Counters come up in two form Asynchronous and Synchronous counters.
How many pins are there in the 74ls93 IC?
We can use the microcontroller or timer IC for pulse input. The 74LS93 IC comes up with two reset pins, two clock pins, and four output pins. The IC is made up of two counters one is mod 2 counter another one is mod 8 counter. The whole IC gives the output 4 bits which counts from 0 to 15 in binary.
