Description
74192 – Presettable Synchronous 4-Bit Up/Down Counter
📄 **Description:
The 74192** is a BCD (Binary-Coded Decimal) Presettable Synchronous 4-bit Up/Down Counter with separate count-up and count-down clock inputs. It counts in decimal (0–9), making it ideal for applications requiring decimal-based counting logic.
This IC supports synchronous operation, which means that all flip-flops within the counter are clocked simultaneously, allowing precise and glitch-free counting. The 74192 also includes presettable inputs for loading a specific starting value and features carry and borrow outputs for cascading multiple counters.
