Product Description
onsemi MC74HC393A is a high-performance silicon-gate CMOS dual 4-bit binary ripple counter designed for versatile digital counting applications. It operates on a voltage range from 2 to 6 V and meets RoHS standards, ensuring compliance with environmental requirements.
The device consists of two independent ripple counters that can be cascaded to create larger count ranges, such as a divide-by-256 counter. Internal flip-flops are triggered by high-to-low clock transitions, and the asynchronous reset is active-high, allowing for quick and reliable resetting of the counter's state.
Outputs are compatible with CMOS, NMOS, and TTL devices, supporting up to 10 LSTTL loads, making it suitable for various interfacing needs in electronic circuits. The low input current of 1 mA contributes to efficient power consumption, suitable for battery-operated and low-power systems.
The MC74HC393A offers robust operation over a wide temperature range (-55°C to 125°C), ensuring it can perform reliably in industrial, laboratory, and commercial environments. Its chip complexity of 236 FETs or 59 equivalent gates underscores its solid design.
Operates at supply voltage from 2 to 6 V. Dual 4-bit ripple counters with parallel outputs. Asynchronous reset active-high for fast state clearing. Output drive capacity up to 10 LSTTL loads. Low input current supporting power efficiency.
High noise immunity typical of CMOS technology. Temperature range from -55°C to 125°C for harsh environments. RoHS compliant and suitable for eco-friendly designs.
This counter IC is ideal for integration in digital logic designs requiring precise counting functions, including industrial automation, instrumentation, and embedded system applications. Its surface mount type enhances PCB design flexibility and manufacturing efficiency.
