CD4536 CD4536BE CD-4536 4536 DIP-16 Package Oscillator Timer IC  Chip Programmable 16 Pin Leads Timer IC

CD4536 is a programmable timer that comprises 24 ripple binary counter stages. The salient feature of this device is its flexibility. The device can count from 1 to 224 or the first 8 stages can be bypassed to allow an output, selectable by a 4-bit code, from any one of the remaining 16 stages. It can
be driven by an external clock or an RC oscillator that can be constructed using on-chip components. The CD4536 is a popular timer IC due to it’s use in high quality electronic timers for AC/DC appliances. CD4536 has a wide array of features such as high noise immunity and efficient thermal compensation. This IC is very simple to use and can be interfaced directly with CMOS, NMOS & TTL devices.

Programmable Timer?

Programmable Timers are simple circuits that offer measurement, display and control in applications that contain variables. They can operate with a single input or, in some cases, a pair of signals. Programmable timers are usually electronic and use digital displays, precise digital set-ability, high accuracy, and fast reset times.

Where to use NE556 IC

The NE556 IC is the dual version of NE555 IC, meaning the NE556 has two timers inside it. As we know 555 ICs have been used for a long time now due to their reliable properties and applications. The NE556 can also be used for all those application additionally since this works with CMOS technology we can have two timers inside a single package with improved characteristics.

So if you are looking for a modern replacement for the 555 Timer IC then NE556 might be the right choice for you.

Difference Between 555 and 556 IC

The NE556 is the successor of the classic 555 Timer IC. It has two Timers inside a single package. This reduces the form factor and complexity of the system. Functionality and pin description wise both 555 and 556 are identical.

How to use NE556 IC

Application wise both NE555 and NE556 are one and the same, so if you want to know the basic of the Timer IC then read through the NE555 page. Since the NE556 is a 14-pin dual timer package there are two sets of all the timer pins (Threshold, Out, Trigger, Control Voltage, Discharge) and both the timer share the same Vcc and ground pins.

Timer IC’s are the most commonly used ICs for timing and Pulse generation applications. They can adopt itself into various applications due to its different operating modes. They are very simple to understand and if we take a look at the components present inside as shown below.

There are three resistors of value 5K, which gives this IC it’s iconic name “555 Timer”. It has dual comparators and flip-flop which will make this IC operated in three different modes such as Astable, Monostable and Bistable(Schimitt) Mode.
