Hello, Welcome to Dasenic

The Fairchild Semiconductor DM74ALS162BN is a 4-bit synchronous binary counter with asynchronous clear. It belongs to the Advanced Low-Power Schottky (ALS) logic series. Functions: 1. 4-Bit Synchronous Binary Counter: Counts sequentially in binary form from 0000 to 1111. 2. Asynchronous Clear: Allows the counter to be reset to 0000 at any time by applying a clear signal. Applications: - Clock and frequency division circuits - Address decoding in computer systems - Time delay measurement circuits - Event counting and sequencing applications Alternative Components: - 74LS161: 4-bit counter without synchronous clear - 74LS193: 4-bit up/down counter with parallel load - 74LS390: Dual 4-bit decade and binary counters - 74LS669: 4-bit binary counter with synchronous clear Embedded Modules: - Clear input: Synchronously clears the counter when activated. - Clock input: Controls the counting sequence. - Outputs: Provide the binary count information. Related Q&A: 1. Can the DM74ALS162BN be cascaded to create larger counters? - Yes, multiple counters can be connected together for extended count sequences. 2. How does the asynchronous clear feature work on this counter? - The asynchronous clear input immediately resets the counter output to 0000 irrespective of clock input state. 3. What is the maximum clock frequency this counter can handle? - The maximum clock frequency is determined by the propagation delay of the internal circuitry. 4. Does the DM74ALS162BN consume less power compared to equivalent TTL counters? - Yes, the Advanced Low-Power Schottky technology used in this IC helps in reducing power consumption. 5. Can this counter be used in microcontroller interfacing circuits? - Yes, it can be used for interfacing and diverse timing applications in conjunction with microcontrollers.
