The 74HC393D,652 is a two 4-bit synchronous binary up/down counter device with a multiplexed input/output designed for counter and frequency division applications. This device can serve both as an up counter and as a down counter, with one of these operation modes selectable depending on the logic state of an associated control signal. The device has a synchronous input, an asynchronous clear input (active low), a multiplexed output, and an asynchronous load input (active low), which many feature pairs share simultaneously. This logic counter can be used in a variety of applications that require data separation and frequency division.

The 74HC393D,652 counter is ideal for applications such as frequency counters, time keeping, and the generation of signals. It utilizes advanced silicon-gate CMOS technology and has a low power consumption. The device has a high-speed operation of 400kHz, and an advanced design which provides asymmetrical 393D,652 outputs from the D- and C- output pins. The 74HC393D,652 is available in 6-pin DIP, 8-pin DIP, and 14-pin DIP packages.

The 74HC393D,652 is a synchronous up/down binary counter. The four data bits can be loaded and can be counted up or down. This device is divided into two 4-bit cascaded counters. A discrete input signal from the external counter selects either the up (01) or down (10) counting direction, while the asynchronous clear and asynchronous load inputs can reset the count to 0000 at any time. During the up counting operation, the count increases by one each time a rising edge occurs on the clock input. The count will cascade to the next higher order counter. During the down counting operation, the count decreases by one each time a positive edge occurs on the clock input.

The 74HC393D,652 logic counter is powered by an external 3.3V or 5V power supply and is protected against static discharge. The device has an adjustable edge sensitivity and is designed for high-speed counting applications. It is a general-purpose device for use in application specific fields. It is compatible with a variety of other devices and can be used in systems that require higher-speed frequency input and output.

The device features a two 4-bit synchronous up/down counter, with the multiplexed output pins which allow access to two outputs from the same internal signal line. It is designed for a wide range of applications including counting, timing, and frequency division. The 74HC393D,652 is ideal for applications such as pulse generators, frequency dividers, time keeping, and data separations. It is easy to design and implement and is highly reliable.

In conclusion, the 74HC393D,652 is a two 4-bit synchronous binary up/down counter device with a multiplexed input/output designed for counter and frequency division applications. It is ideal for applications such as frequency counters, time keeping, and the generation of signals. It features a two 4-bit synchronous up/down counter, with the multiplexed output pins which allow access to two outputs from the same internal signal line. It is designed for a wide range of applications including counting, timing, and frequency division. The 74HC393D,652 is a reliable and effective logic counter.
