LS7222 Overview
The LS7222 is a programmable electronic lock implemented in a monolithic CMOS integrated circuit. The circuit contains all the necessary memory, decoder and control logic to make a programmable "keyless" lock system to control electro-mechanical locks. Input is provided by a matrix keypad whose maximum allowable size is 4 x.
