The SN74LV393ATPWRQ1 is an integrated circuit (IC) device which falls within the broader category of Logic-Counters, Dividers. This device provides two counters and a two–bit comparator. It is available in an 8-dip or an 8-soic package and is rated for 1.65 to 5.5 volts.

In terms of applications, the SN74LV393ATPWRQ1 can be used in a variety of digital logic applications such as generating multi-bit code generators, rate multipliers, frequency dividers, pulse width modulation (PWM) generators, pulse-shaping circuits, frequency counters, divide-by-N counters, edge detectors and delay generators. The SN74LV393ATPWRQ1 is also commonly used in microprocessor-based systems to decode multiple address lines, sequence pulses, and latch control signals.

The SN74LV393ATPWRQ1 is a synchronous dual-modulus presettable counter. It is capable of frequency division between 2 modulus values set for each counter independently. The first counter is a modulus-16 binary counter and the second counter is a modulus-4 binary counter. The preset input is used to program the initial count of each counter. The output is in logic state “0” when both counter values match the preset input.

The SN74LV393ATPWRQ1 operates with two separate counters that are both clocked by the same clock signal. Both counters have their own preset inputs that are used to program the initial count. The first counter divides the input clock frequency by a factor of sixteen, while the second counter divides the output of the first counter by a factor of four. The output of the counters is used to trigger a comparator which in turn resets the counters when both preset inputs match. The reset signal is used as the output signal.

The SN74LV393ATPWRQ1 also includes a two-bit comparator that can be used to measure the difference in two bits of input data. This comparator can be used to compare the output of two different counters and advance or reset the output signal of the counters accordingly. This is especially useful in applications such as motor control or rate stabilization. For example, the comparator can be used to measure the difference between the actual speed of a motor and the desired speed, and then adjust the output signal of the counters to change the speed of the motor.

The SN74LV393ATPWRQ1 is part of the low-voltage family of logic ICs from Texas Instruments. It is designed to operate over a wide voltage range of 1.65 to 5.5 volts and is capable of driving low-voltage and high-level outputs. It is a low-power device and consumes less than 1 mW at 4.5 volts.

The SN74LV393ATPWRQ1 is a versatile, low-power device that can be used for a variety of digital logic applications. It is capable of frequency division between two modulus values, and is able to measure the difference in two bits of input data. With its wide operating voltage range, it is an ideal choice for any low-voltage logic application.
