Frequently Asked Questions
What is the CD74HCT393M and what does it do?
The CD74HCT393M is a dual 4-bit binary ripple counter IC from Texas Instruments. It contains two independent 4-bit counters, each with its own clock input, active-low reset, and four output lines (Q0–Q3), enabling frequency division by up to 16 per channel.
What are the key electrical specifications of the CD74HCT393M?
The CD74HCT393M operates on a 5V supply (4.5V to 5.5V range), features TTL-compatible input thresholds (VIH min 2V, VIL max 0.8V), and provides CMOS output levels. It supports clock frequencies up to 45 MHz typical at 25°C with propagation delay around 17 ns.
What package does the CD74HCT393M come in?
The CD74HCT393M is available in a 14-pin SOIC (Small Outline IC) surface-mount package, suitable for automated PCB assembly. The 'M' suffix denotes the SOIC package in Texas Instruments' naming convention.
What are typical applications for the CD74HCT393M?
Typical applications include digital clock dividers, frequency counters, address counters for memory systems, event counting circuits, timer circuits in embedded systems, and programmable logic sequences in industrial and consumer electronics designs.
How do I reset the counters on the CD74HCT393M?
Each counter has an active-low Master Reset (MR) pin. Applying a logic LOW to MR asynchronously clears all four output bits (Q0–Q3) to zero, independent of the clock signal. The reset is immediate and does not require a clock edge to take effect.
