LS7212 Datasheet (LSI Computer Systems) - PROGRAMMABLE DIGITAL DELAY TIMER

LS7212, PROGRAMMABLE DIGITAL DELAY TIMER

The LS7211/LS7212 are monolithic CMOS integrated circuits for generating digitally programmable delays.

The delay is controlled by 8 binary weighted inputs, WB0-WB7, in conjunction with an applied clock or oscillator frequency.

The programmed time delay manifests itself in the Delay Output (OUT) as
