The SN74HC193PWRG4 is a 4-bit binary counter housed in a 16-pin plastic dual-in-line (PDIP) package. It is part of the family of logic devices, grouped under the general heading of counters, dividers, rip-through counters and ripple counters. This type of logic device is used as a way of counting some type of event either up or down, as well as controlling the time between events.

The SN74HC193PWRG4 functions as an asynchronous (ripple) binary up/down counter, meaning it counts either up or down depending upon the input signals provided. The most important features that the SN74HC193PWRG4 can provide are the ability to count in either the positive or the negative direction, counting in both directions in one cycle, as well as being extremely low-power and fully static – meaning all of its circuits are powered by the signal source.

The SN74HC193PWRG4 contains two identical 4-stage ripple-through, up/down binary counters. When both A and B input pins receive a low signal, the counters can be set up to either count up or down. If the A input is high and the B input is low, the counters operate as up/down counters, counting up on clock pulses at the CLK input. Conversely, if the A input is low and the B input is high, the counters count down on incoming pulses at the CLK input.

The SN74HC193PWRG4 contains internal carry lookahead logic which allows its counting capacity to be extended to any number of binary counters connected together with the least amount of propagation delay. This means that the gates for the extended counting range do not have to go through the same number of delays as the ripple counter itself. This is important because it allows for greater speed and efficiency when extended counting is needed.

The SN74HC193PWRG4 has a wide variety of applications in many industrial and commercial fields. Examples of its uses include frequencyg counting, pulse generation, rate conversion, pulse-width modulation, duty-cycle control, event counting for event timers and process controllers and more.

The SN74HC193PWRG4 is an economical way to provide a variety of functions in any system. It is easy to set up, with the internal counter and carry lookahead logic allowing for fast counting. The wide range of applications makes it an ideal choice for many industrial and commercial environments. Its low power draw and static design allow it to be used in environments where power is a concern and reliability is paramount.
