74LS85 or SN54/7485 is a 4-bit magnitude comparator of two binary format inputs. In electronics devices besides addition and subtraction comparison of binary numbers is also important to perform the operations. To solve this issue, we use TTL based comparators. The basic function of the comparator is to compare the two input bits and then … Read more
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 2n … Read more
74LS48 is a BCD to seven segments decoder that is used to display numbers decoded in binary coded decimal format. The 7-Segment is a small seven LED-based device use to represent a single numeric value from 0 to 9. Each 7-Segment has seven input pins to light up a single led in the seven segments. … Read more
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. Both these types of counters use the flip flops … Read more
The IC 74LS145 is a TTL based BCD to Decimal decoder used to drive the ten binary outputs on the base of four binary inputs. The IC consist of eight inverter and ten NAND gates which have four inputs. These total eighteen gates come up with a smart circuit that gives ten output through the … Read more
6N135 is a single channel high speed optocoupler based on two photodiodes and a transistor output. It works by providing an electrical insulation shield between an input side and an output side. Compare to conventional optoisolators such as 4N24, MOC2031, 6N135 offers a very high speed bits transmission rate due to separate biasing voltages photodiode … Read more
74LS14 is a Schmitt trigger hex 8-bit inverter IC. In electronics devices, Schmitt Trigger is one the comparator-based circuit which gives the output on the based the previous output. In Schmitt Trigger the input value can be analog or digital but the output will be in two forms 1 or 0. Any circuit is convertible … Read more
74LS08 is a Quadruple 8-bit Two Input AND IC. Gate AND gate is a digital circuit used to convert the logic state to a specific logic. In AND gate two logics state signals are used. The first one is HIGH, which is also known as 3-5Volts and the second one is LOW which is represented … Read more
74LS04 is a 2 input quadruple 8-bit NOT gate IC. Inverter in logic converters is an electronics device whose basic functions are to invert the incoming logic weather it is HIGH or LOW. They are also known as NOT gates. Inverters are easy to design using NMOS and PMOS transistors. They have only one input … Read more
74LS IC series comes up with multiple gates. It provides us with compact design and multiple packages of the same IC. Here we will discuss 74LS02. 74LS02 also know as 7402. IT comes up with 4 internal NOR gate. IC 7402 comes up in multiple packages with 14 pins and 2 inputs 4-NOR gates. NOR … Read more
