The NC7SB121 is a low voltage UHS single SPST wide bandwidth normally open analog switch from Fairchild Semiconductor Corporation. It has 7.2Ω switch connection between two ports, minimal propagation delay, low ICC, zero bounce and other features.
The NC7SB121 is an ultra high-speed (UHS) CMOS compatible single-pole/single-throw (SPST) analog switch or 1-bit bus switch. It features a low on-resistance, allowing inputs to be connected to outputs with minimal propagation delay and without generating additional ground bounce noise. The device is organized as a 1-bit switch with a switch enable (OE) signal.
