What is 74LS93?

The 74LS93 is a 4-bit binary counter made of two up-counters. The IC consists of a mode-2 up-counter and a mod-8 up counter. Can be combined as mod-8 counter or divide by 2 or divide by 8 applications. It is built using four JK Flip Flops.

Which of following pin is NC pin in IC 74LS93?

Pin 13 is also the NC pins of the IC.

Is 74LS93 is an asynchronous counter IC?

The 74LS93 is a 4-bit binary counter made of two up-counters. The IC consists of a mode-2 up-counter and a mod-8 up counter. It is built using four JK Flip Flops….74LS93 Pin Configuration.

What is ic7493?

IC 7493 is a 4 bit binary counter IC, it is composed of 4 JK Flip Flop. Out of which 3 are connected together and 1 is alone, it is consists of a mod 8 counter and a mod 2 counter. Together they make a mod 16 counter.

Which IC can be used as up down counter?

Special dual purpose IC’s such as the TTL 74LS193 or CMOS CD4510 are 4-bit binary Up or Down counters which have an additional input pin to select either the up or down count mode.

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.

Should I ground NC pins?

The NC pin can be connected to ground to improve thermal capacity or heat dissipation (if the option is applicable for the device as stated in the datasheet). An NC pin, by default, should be left unconnected or floating because most of the time, it is only used by manufacturers to test the device before distribution.

What does NC pin mean?

Not Connected Pin (NC pin) or Not Connected Terminals are pins found on various integrated circuit packages. Those pins have no functional purpose to the outside circuit (but may have unexposed functionality). Those pins should not be connected to any of the circuit connections – i.e. they should be left floating.

How many FFS are required for mod counter?

Answer. 3 D- Flip flops are needed for implementation of Mod-6 counter because you need 3 bits in order to represent 6. In the same way, we require 4 flip flops for implementation of Mod-11 counter i.e., For 11 we require 4 bits.

Why the ripple counter is named so?

Asynchronous counters are also called ripple-counters because of the way the clock pulse ripples it way through the flip-flops.

What is a mod-10 counter?

In general, any arrangement of a “m” number of flip-flops can be used to construct any MOD counter. A common modulus for counters with truncated sequences is ten (1010), called MOD-10. A counter with ten states in its sequence is known as a decade counter. Decade counters are useful for interfacing to digital displays.

What is 74ls93 IC?

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. This is compatible with any microcontroller or TTL based devices.

How many 7-segment displays can be used with 74ls93?

Although, 74LS93 is a 4 bit counter and it can counter from 0-16 in binary and we can use two seven-segment displays to show counter values. We have used only one 7-segment display in this example. Therefore, we have to reset the counter states after it reaches to binary value 9.

How to use a 74ls93 binary counter?

The pins we are going to use for the 74LS93 binary counter are two input pins, two reset pins, and four output pins. First, connect the powers and then connect the first clock pin (Pin 1) with the last bit (Pin 12) . We will discuss later why we did that. After that connect the reset pins with the ground.
