CD74HC193M96E4 is an adjustable 4-bit binary counter that contains four individual flip-flops and counts in either it’s binary or BCD (Binary-Coded Decimal) formats. In binary counting mode, after each clock pulse or divided system clock pulse is applied to its clock input (CP), the counter will sequentially count up to a preset value and then reset to zero, also known as zero count. It also features two buffered outputs of the two least significant bit stages, QCout and QCoutb, for creating patterns. The clock parameters of this device offer improved triggering reset time for faster counting operations.

The CD74HC193M96E4 is typically grouped into the logic families, counters, dividers and can be used for a variety of applications such as clocks, computer systems and instrumentation.

The CD74HC193M96E4 has a wide range of applications, with the most common being frequency division, counter and timer applications.

The CD74HC193M96E4 can be used in frequency division applications, where it is used to divide a high frequency signal into a low frequency signal. The CD74HC193M96E4 can also be used as a counter, where it is used to count pulses on an input line. Finally, the CD74HC193M96E4 can be used as a timer, where it is used to measure time intervals between two events.

The CD74HC193M96E4 is a fairly straightforward device when it comes to its operation and it’s working principle. The CD74HC193M96E4 functions on positive-edge triggered clock mode and consists of four individual TTL flip-flops. Each flip-flop has an inherantly asynchronous reset, that resets the count to zero when it is activated. When the clock input, is applied, the count is incremented by one for every positive-going transition of the clock. When the maximum count is reached, the counter resets it’s count and starts again.

The count is decoded by two 4-bit output Decoder, QCout and QCoutb, which generate the output codes of 0-15 and 15-0, respectively in Binary-Coded Decimal format. In Binary-Coded Decimal (BCD) format, the four outputs together show the count, in binary, from 0-15. In binary counting mode, the count is sequentially incremented by one for every positive edge at the clock input.

When the counter reaches the preset value, the count is reset to zero, the buffer output for the two least significant bit stages, QCout and QCoutb, produces a pattern of four bits. This pattern can be used to control a display and to generate a zero-count reset of the display.

The CD74HC193M96E4 also has some advanced features, like the pin-strapped synchronous reset, which allows the counter to be reset when the synchronous reset is activated. This reduces the possibility of errors during the counting. Another feature is the “Set” input, which allows the counter to count at a specific value. This comes in handy when multiple counters are used in a system to synchronize the operation of the individual counters.

The CD74HC193M96E4 is a simple yet versatile device that can be used for a variety of purposes. It does have drawbacks, such as the limited clock speed and total count, but with its advanced features, the CD74HC193M96E4 is well suited for many different applications.
