2:2 Differential-to-HCSL Multiplexer W/Low Input Level Alarm

The 851S201I is a high performance 2:2 Differential-to-HCSL Multiplexer with a 2 output fanout buffer. The 851S201I operates up to 250MHz and accepts HCSL and other low level differential inputs levels. Input level detection circuitry is available to flag input levels that drops below a specified value and on the selected input. This signal is latched until the status is reset via the alarm reset input. The 851S201I is packaged in a small 3 x 3 mm 16 lead VFQFN package, making it ideal for use on space constrained boards.
