PROGRAMMABLE DIGITAL DELAY TIMER

DESCRIPTION: The LS7215 and LS7216 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 Outpu
