LM8333 General Description

The LM8333 is a general-purpose controller for matrixaddressed keypads which provides an ACCESS.bus (I2Ccompatible) interface to a host microcontroller. It offloads the burden of keyboard scanning from the host, while providing extremely low power consumption in both operational and standby modes. I.
