LS7211N Datasheet (LSI) - PROGRAMMABLE DIGITAL DELAY TIMER

LS7211N, PROGRAMMABLE DIGITAL DELAY TIMER

The LS7211N and LS7212N are 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 a
