Product Overview: 73HC393N Dual 4-bit Binary Ripple Counter by NXP

The 73HC393N is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). Manufactured by NXP, a leading semiconductor company, this integrated circuit (IC) is designed to be a dual 4-bit binary ripple counter. It is primarily used in counting applications in a wide range of electronic devices due to its reliable performance and versatility.

The 73HC393N is composed of two 4-bit ripple carry counters, which can be used independently or cascaded to create an 8-bit counter. Each counter has a divide-by-two section and a divide-by-eight section, which are triggered by a HIGH-to-LOW transition on the clock inputs. The counters advance on the falling edge of the clock pulse, making them suitable for a variety of timing and sequencing applications.

Key Features:

• High-Speed Operation: The 73HC393N operates at high speeds, matching the performance of equivalent LSTTL counters.
• Wide Operating Voltage Range: It can operate on a wide voltage range from 2V to 6V, providing flexibility for use in various circuit designs.
• Low Power Consumption: Its CMOS technology ensures low power consumption, which is critical for battery-operated devices.
• Output Capability: The IC can drive up to 10 LSTTL loads, making it suitable for driving multiple devices in a circuit.
• Master Reset: The inclusion of a master reset function allows for the quick and synchronous resetting of both counters.

The 73HC393N is available in a 14-pin DIP (Dual In-line Package) which makes it easy to handle and integrate into a variety of electronic circuits. Its robustness and durability are ensured by NXP's commitment to high-quality manufacturing standards.

Whether it's used in digital counters, frequency dividers, time delay circuits, or as part of a microprocessor's clock circuitry, the 73HC393N from NXP stands as a reliable and efficient choice for designers looking to incorporate a binary counter into their electronic projects.
