Synchronous Counter IC SN74162

Synchronous Counter IC SN74162

Here, in this article we will discuss about Synchronous Counter IC SN74162, its key parameter and its application. Description of Synchronous Counter IC SN74162 Synchronous counters are available in a large variety of sizes and with a number of standard output decoders. The essential features of this type of counter can be seen from the illustration of figure 1(a). Each of the flip-flops (FF) is controlled by the clock signal. Whatever data are entered must be entered in synchronism with the clock, because only when clock enables each FF can…

Counter or Divider IC

decade counter or divider IC

The essential function in all counter or  divider IC is performed by the basic flip-flop (FF) which changes states only on either a positive or a negative going transaction. If a pulse or square-wave signal is applied to the input of an FF with positive logic, it will change state only on the rising edge of the signal. For every two pulses or square waves at the input, only one square wave will be available at the output. Every FF has a Q and Q bar output, one being the…

Non-Inverting 3 State Buffer | SN74126

Non-Inverting 3 State Buffer

Here in this article we will discuss about Non-Inverting 3 State Buffer, its key parameters and its applications. Non-Inverting 3 State Buffer Description: This IC contains six identical non-inverting buffers, arranged in two groups, as illustrated in figure 1. The first group of two buffers is controlled by the “disable A” signal. The seconds group of four buffers is controlled by the “disabled B” signal. This provides three possible output states. When the respective disable signal is 0, the output will be the same as the input, with the usual…

True Complement Buffer IC | CD4041

True Complement Buffer IC | CD4041

In the article “True Complement Buffer IC | CD4041” we will discuss about true complement buffer IC, it’s key parameters and application. Description of True Complement Buffer IC | CD4041 Usually available with four identical circuits on a single IC, this buffer provides both the true output and its complement. As illustrated in figure 1, the complement of the input is provided by a single inverter stage while the true output is provided by two stages. The circle at the input of the second stage indicates that, while this circuit…

Strobed Buffer or Inverter IC | CD4502

Strobed Buffer or Inverter IC

In this article, we will learn about strobed buffer or Inverter IC CD4502, its parameter, truth table and its application. Description of Strobed Buffer or Inverter IC This IC provides the basic buffer or inverter function as well as two additional control functions. As illustrated in figure 1, all six inputs are controlled by a single “inhibit” signal, and all six outputs are controlled by a single “disable” signal. This permits each of the six inputs and outputs to have a total of three possible states, as indicated by the…
