- Brand: Renesas Electronics - Model: 74HC161TELL-E - Category: Integrated Circuits (ICs) - Description: 4-Bit Binary Counter - Package: TSSOP-16 Functions: - The 74HC161TELL-E is a synchronous presettable binary counter with an asynchronous reset input. - It counts on the rising edge of the clock signal and can be preset to any number between 0 and 15. - It features parallel enable inputs, allowing for easy cascading of multiple counters. Applications: - Binary counting in digital systems. - Frequency division and time measurement applications. - Address generation for memory devices. - Sequence generation in control systems. Alternative Components: 1. SN74HC161N - Texas Instruments 2. CD74HC161E - Texas Instruments 3. MC74HC161N - ON Semiconductor Embedded Modules: - The 74HC161TELL-E can be integrated into larger digital systems for functions like input/output expansion, data processing, and control logic. Related Q&A: 1. Can the 74HC161TELL-E be used as a frequency divider? - Yes, the 74HC161TELL-E can function as a frequency divider by counting input clock pulses. 2. What is the maximum clock frequency the 74HC161TELL-E can handle? - The maximum clock frequency is typically specified by the manufacturer and is usually in the range of tens of megahertz. 3. How do I cascade multiple 74HC161TELL-E counters for extended count ranges? - You can cascade multiple counters by connecting the carry-out (CO) of one counter to the clock input (CLK) of the next counter. 4. Does the 74HC161TELL-E have a power-down mode for low-power applications? - The 74HC161TELL-E does not typically have a dedicated power-down mode, but its power consumption can be reduced by gating the clock signal. 5. What are the voltage and temperature operating ranges for the 74HC161TELL-E? - The operating voltage range is usually around 2V to 6V, and the temperature range is typically from -40°C to 85°C.
