Fast switching speeds, low ON-resistance, and low power-consumption make these devices ideal for singlecell battery powered applications. These highly-reliable devices operate from a to +5.5V supply, are differentiated by inverted logic, and support break-before-make switching. With low ON-resistance RON , RON matching, and RON flatness, the devices can accurately switch signals for sample and hold circuits, digital filters, and op-amp gain switching networks.
