Description

·The LS7210 is a monolithic MOS integrated circuit programmable digital timer that can generate a delay in the range of 6ms to infinity.

·The delay is programmed by 5 binary weighted input bits in combination with the time base provided. The chip can be operated in four different modes: Delayed Operate, Delayed Release, Dual Delay and One Shot. These modes are selected by the control inputs A and B.
