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.

FEATURES:

• Programmable Delay from 6 ms to Infinity

• Can be Cascaded for Sequential Events or Extended Delay

• +4.75V to +15V Operation (Vss -VDD)

• On Chip Oscillator or External Clock time base

• High Noise Immunity

• LS7210 (DIP), LS7210-S (SOIC)-See Figure 1
