Description

The 74HC393D is a dual 4-bit binary counter IC from the 74HC series of high-speed CMOS logic devices. It consists of two independent 4-bit counters that can be cascaded to create an 8-bit counter. Each counter in the 74HC393D has a clock input (CP), a reset input (MR), and four parallel outputs (Q0 to Q3). The counters divide the clock frequency by up to 16 through binary counting.
Key features include:
- High-speed performance with typical propagation delays.
- Low power consumption due to CMOS technology.
- Wide operating voltage range (typically 2V to 6V).
- Standard pin configuration, making it compatible with other TTL and CMOS ICs.
- Each counter can be asynchronously reset using the master reset input.
The 74HC393D is commonly used in applications requiring frequency division, sequential counting, or digital timing. It is widely used in digital electronics projects and designs, including timers, frequency counters, and state machines.

Features

The 74HC393D is a high-speed Si-gate CMOS device that features a dual 4-bit binary ripple counter. It has two independent 4-bit counters, each with a clock input, master reset, and outputs for each of the four bits. The device operates with a supply voltage range of 2V to 6V and is compatible with TTL logic levels. It features a low power consumption and high-speed operation due to its CMOS technology. The counters are triggered on the negative edge of the clock input and can be reset asynchronously to zero using the master reset input. The 74HC393D is packaged in a standard SO-14 surface-mount configuration. Key characteristics include its ability to count binary sequences in response to clock inputs, making it suitable for applications like frequency division, event counting, and timing applications. The device is known for its robustness, reliability, and ease of use in digital circuit designs.
