The Onsemi74AC169MTCX is a 4-bit binary synchronous counter, often referred to as a divide-by-16 counter. It belongs to the ICs category and is commonly used in various digital applications for counting purposes. Functions: 1. Binary Counter: It can count in binary from 0000 to 1111. 2. Synchronous Operation: The counter increments its count synchronously with an external clock signal. 3. Reset Capability: It has a reset input that allows the counter to be cleared to all zeros. 4. Cascade Ability: Multiple ICs can be cascaded to create wider counters by connecting the carry-out of the first counter to the clock input of the next. Applications: 1. Frequency Division: Used for frequency division in clock generation circuits. 2. Sequential Logic: Forms the building block for more complex sequential logic circuits. 3. Digital Signal Processing: Utilized in digital signal processing algorithms that require counting or sequencing. 4. Automated Test Equipment (ATE): Found in ATE systems for testing integrated circuits. Alternative Components: 1. CD4060: 14-stage binary counter and oscillator. 2. HC161: 4-bit binary counter with synchronous reset. 3. CD4040: 12-stage binary ripple counter. 4. 74LS193: Synchronous 4-bit up/down binary counter. Embedded Modules: 1. 74AC169: 4-bit binary synchronous counter IC. 2. TCXO: Temperature Compensated Crystal Oscillator for clock reference. 3. Digital Input Buffer: Input protection and voltage level translation circuitry. --- Related Q&A: 1. What is the maximum clock frequency supported by the Onsemi74AC169MTCX? - The maximum clock frequency supported by the Onsemi74AC169MTCX is typically in the range of 50-100 MHz, depending on operating conditions. 2. How does the reset input function in the Onsemi74AC169MTCX work? - The reset input, when activated (low logic level usually), clears the counter to all zeros irrespective of the clock input, allowing for a controlled reset of the counting sequence. 3. Can the Onsemi74AC169MTCX be cascaded with other counters to create larger counting sequences? - Yes, the Onsemi74AC169MTCX can be cascaded by connecting the carry-out from one counter to the clock input of the next counter, enabling the creation of wider counting sequences. 4. What is the power supply voltage range for the Onsemi74AC169MTCX? - The Onsemi74AC169MTCX typically operates within a power supply voltage range of 2V to 6V, making it compatible with a wide range of digital systems. 5. In what type of packaging is the Onsemi74AC169MTCX available? - The Onsemi74AC169MTCX is commonly available in a 16-pin TSSOP (Thin Shrink Small Outline Package), which is a surface-mount package suitable for compact electronic designs.
