IC BINARY COUNTR DL 4BIT 14SOICManufacturer: onsemi
Categories: Counters, Dividers
Quality Control: Learn More
The onsemi DM74LS393M is a dual 4-bit binary ripple counter. This TTL-compatible device features two independent 4-bit counters, each offering a count rate of up to 25 MHz. The counters are asynchronous and increment on the negative edge of the clock input. Each 4-bit counter includes parallel outputs for each bit position, enabling easy cascading for higher bit-count applications. Reset functionality is asynchronous, allowing immediate clearing of the counter states.
This component is housed in a 14-SOIC package, suitable for surface-mount applications. The operating voltage range is 4.75 V to 5.25 V, with an operating temperature range of 0°C to 70°C. The onsemi DM74LS393M is commonly utilized in digital logic systems for frequency division, timing circuits, and general-purpose counting applications across various industrial and consumer electronics sectors.
