LS7222 General Description
·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 4.
·The LS7222 can be programmed to recognize 3 different codes: one to lock (Arm), one to unlock (Disarm), and one to unlock and trigger an alarm (Duress). Programming is done via the keypad inputs. Any entry from the keypad (when not in the program mode) which does not match one of the 3 programmed codes causes the Tamper output to become active.
·The monolithic, low power CMOS design of the LS7222 enables it to be designed into typical battery backed-up and automotive type security systems.
