LS7212N, 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
