Onsemi MC74ACT161D Environmental and export classification status description

- Part Number: OnsemiMC74ACT161D - Manufacturer: ON Semiconductor - Description: 4-Bit Binary Counter - Package: 16-SOIC package Functions: - Counts up on the rising edge of the clock input - Has a synchronous set feature that allows the user to preset the counter to a desired value - Can be reset asynchronously, which clears the counter to its zero state Applications: - Digital frequency dividers and counters - Numeric displays and registers - Timers and event counters in various digital systems - Sequential logic circuits Alternative Components: - 74HC161: 4-bit synchronous binary counter - CD4017: Decade counter with 10 decoded outputs - SN74LS393: Dual 4-bit binary counter Embedded Modules: - Embedded in applications where precise counting and frequency division is required - Embedded in various microcontroller projects for counting and timing purposes Related Q&A: 1. What is the difference between synchronous and asynchronous counters? Synchronous counters have all flip-flops (or counter stages) triggered simultaneously by a common clock signal. Asynchronous counters have the toggle inputs of succeeding stages triggered by the output of the preceding stage. 2. How can I check if my binary counter IC is working correctly? You can check the functionality by applying clock pulses, monitoring outputs to ensure proper counting sequence, and using preset and clear functions as needed. 3. Can I cascade multiple binary counters together? Yes, you can cascade multiple binary counters to increase the count size. Connect the carry output of the lower counter to the clock input of the higher counter. 4. What is the maximum frequency at which OnsemiMC74ACT161D can operate? OnsemiMC74ACT161D typically can operate at clock frequencies up to several megahertz, depending on the specific operating conditions and voltage levels. 5. How do I interface OnsemiMC74ACT161D with a microcontroller? You can interface the IC with a microcontroller using digital I/O pins to provide clock pulses, set, or reset signals, and monitor the count output for further processing in your project.
