概要

Description

The SN74HC393N is a high-speed silicon gate CMOS device that functions as a dual 4-bit binary counter. It is part of the 74HC family of logic integrated circuits and is designed to operate in a wide voltage range, typically from 2V to 6V, making it suitable for various applications. This IC features two independent 4-bit counters, which can be cascaded to create larger counters if needed. It has a synchronous design, meaning that all changes to the counter occur on the rising edge of the clock signal, ensuring precise timing operations.
The SN74HC393N is known for its low power consumption and high noise immunity, making it ideal for battery-powered and portable devices. Additionally, its outputs can drive loads of up to 10 low-power Schottky TTL loads, providing flexibility in interfacing with other digital circuits. The device comes in a 14-pin dual in-line package (DIP), making it easy to handle and integrate into breadboards and prototyping platforms. Its applications include frequency division, event counting, and time delay generation in digital electronics.

1. GND (Pin 7): Ground.
2. VCC (Pin 14): Positive voltage supply.
3. Q0A, Q1A, Q2A, Q3A (Pins 1, 2, 3, 4): Output pins for the first 4-bit counter.
4. Q0B, Q1B, Q2B, Q3B (Pins 13, 12, 11, 10): Output pins for the second 4-bit counter.
5. CLOCK A (Pin 5): Clock input for the first counter.
6. CLOCK B (Pin 9): Clock input for the second counter.
7. CLEAR A (Pin 6): Asynchronous clear for the first counter.
8. CLEAR B (Pin 8): Asynchronous clear for the second counter.
The CLEAR pins are used to reset the counters to zero, independent of the clock. The counters operate on the rising edge of the clock signals.
