The CD40193BPWR is part of the 4000 CMOS integrated circuit family and offers a wide range of features and benefits. It is typically used as a logic – counters, dividers – to control the sequencing of logic circuits. This product from Texas Instruments is designed for logic level asynchronous applications requiring high output drive capability.

In this article, we’ll discuss the application field of CD40193BPWR and its working principles. First, let’s look at the application field.

Application Field of CD40193BPWR

The CD40193BPWR can be used in various applications, such as counter and frequency divider circuits, edge triggered flip-flops, shift registers, code converters and data selectors or multiplexers. This logic function performs the transition by monitoring the input voltage transitions from High to Low and Low to High. The output is available at the output terminal of the logic device.

The following lists some of the most common ways the CD40193BPWR is used:

• To control timing functions in industrial and consumer equipment.
• To control outputs in motor control systems.
• As a counter and frequency divider in communication systems.
• As a sequencer to drive display panel.
• As a counter and frequency divider in control systems.
• To develop advance logic applications.

The CD40193BPWR contains two independent 4-bit switchable counters and an 8-bit shift register. The shift register is a parallel-in, serial-out D-type initialization register with a user-selectable -clock input.

Working Principle of CD40193BPWR

The CD40193BPWR operates as a set of 4-bit counters. The 4-bit counter (Counter A) counts pulses from the clock input and toggles the A output upon reaching 16 pulses. The 4-bit counter (Counter B) counts pulses from the A output and toggles the B output upon reaching 16 pulses. The 8-bit shift register is driven by the pulse from the B output, shifting the data out of the register on each pulse.

The counters (A and B) are initialized separately. Each 4-bit counter has its own Reset, Clock, and Count_Enable inputs. When the Reset and Clock inputs are connected together the counter will count pulses on the Clock input. When the Count_Enable input is connected to the Clock input, the counter will count on the falling edge of the Clock.

To reset the counters, the Reset inputs of both counters must be connected together. When the Reset input is connected to a high logic level, it resets the counter (setting all 4-bits to zero) when the count sequence reaches the end of the sequence.

The shift register consists of 8 D-type flip-flops, a Reset input, and a Clock input. The Reset input can be connected to either a high or low logic level, which sets all the flip-flop’s output states to either high or low. The Clock input is connected to the B output of the counter, and clocking data into the register on the rising edge of the Clock.

The data enters the register from the data inputs (D0 through D7), which can be connected to either constant logic levels, or to data sources such as keyboard buttons or switches. The data is shifted along the register with each pulse of the Clock and is available at the output of the register.

The CD40193BPWR is an excellent device for applications requiring high output drive capability. Whether you are design a counter and frequency divider, a shift register, or a sequencer, the CD40193BPWR will provide you with the performance you need.
