Additional Details

The AM25LS2519/BRA is a member of the low-power Schottky (LS) TTL logic family, offering a balance between speed and power consumption. It typically features a maximum clock frequency of 25 MHz. It includes inputs for clock, up/down control, and data preset. The outputs provide the current count value in either BCD or binary format. The asynchronous clear input allows for resetting the counter to zero at any time. The programmable count length feature enables creating custom counting sequences. The synchronous operation ensures that all flip-flops change state simultaneously, eliminating timing skew and improving accuracy. The device is typically packaged in a DIP (Dual In-line Package) for easy prototyping and board assembly. It requires a 5V power supply for operation. Rochester Electronics specializes in providing long-term support for discontinued components, ensuring that customers can continue to use the AM25LS2519/BRA in their existing and future designs. This part is frequently used in legacy equipment where a direct replacement is needed to maintain system functionality. The high-speed capability and synchronous operation make it suitable for demanding counting applications. Its versatility allows it to be used in a wide range of digital systems.
