34972 Datasheet | NXP Semiconductors

features a 22-to-1 analog multiplexer for reading inputs as analog. The analog input signal is buffered and provided on the AMUX output pin for the MCU to read. The 34972 device has two modes of operation, Normal and Sleep. Normal mode allows programming of the device and supplies switch contacts with pull-up or pull-down current as it monitors switch change of state. The Sleep mode provides low quiescent current, which makes the 34972 ideal for industrial products requiring low sleep-state currents. This device is powered by SMARTMOS technology.
