M74HC393RM13TR is a dual 4-bit binary counter with complementary outputs suitable for operation from a single power supply over a wide voltage range. These devices feature two identical, fully synchronous, 4-bit counters. Counters feature separate clocks and reset inputs for each count stage. The state of each stage may be observed at a complementary pair of outputs, one twos compliment and one twos complement. When used for the count mode, control inputs permit the connection of counters in either a cascade or ripple type configuration.

M74HC393RM13TR is categorized as Logic - Counters, Dividers, signifying its application and its working principle. M74HC393RM13TR incorporates two identical, generally synchronous counters within the same package, which are meant to count up or down, depending on the input control signals provided externally. When the input control signal is at logic high, the counter works in count up mode. When the input control signal is at logic level low, the counter works in count down mode. It has two reset conditions, one active low and the other active high. The active low reset condition cleans out any third party interferences and sets the count to zero, while the active high reset condition re-establishes the count to an initial state.

M74HC393RM13TR is designed for applications that require: cascade connection, data holding; ripple control; high pulsed current; counting and branching; logic-level delay; shift register interfaces; and statistical counters. With its synchronous operation, this device is capable of counting up to 15 and has one carry-bit output. When used in cascade mode, the carry-bit output allows easy and accurate connection to other counters of the same type. Additionally, signals coming in from external sources can be pre-scaled, i.e., slowed down or speeded up, before they reach other counters.

Due to its small size, high speed, low power characteristics, M74HC393RM13TR is suitable for many other applications such as: digital signal processor (DSP) applications; traffic light control; vending machine; frequency measurements; encoders; and controllers.

In conclusion, M74HC393RM13TR is a dual 4-bit binary counter with complementary outputs suitable for operation from a single power supply over a wide voltage range. It features two identical, fully synchronous, 4-bit counters and has two reset conditions, one active low and the other active high. The device is categorized as Logic - Counters, Dividers and can be used in applications that require data holding, ripple control, high pulsed current, counting, branching, logic-level delay, shift register interfaces, and statistical counters. Due to its small size, high speed, and low power characteristics, it is suitable for many other applications such as frequency measurements, encoders and controllers.
