Programmable Digital Delay Timer (14 Pins)

LS7210-S, LS7210

The LS7210 is a MOS 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…

Programmable Digital Delay Timer (18 Pins)

LS7211N-S, LS7211N, LS7212N-S, LS7212N

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…

Programmable Digital Delay Timer (14 Pins)

LS7213R-S, LS7213R

The LS7213R is a CMOS integrated circuit for generating programmable time delays. The delay is initiated by a logic transition at the TRIGGER input and the completion of the delay is marked by a change of status at the OUT1 and OUT2 outputs. Three inputs, D1…

Programmable Digital Delay Timer (20 Pins)

LS7215-S, LS7215, LS7216-S, LS7216

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…

Light-Activated Programmable Timer (8 Pins)

LS7217-S, LS7217

The LS7217 is a programmable Timer IC designed to turn on a relay at night and turn off the relay at dawn or after a selectable number of hours. Dusk-to-Dawn duration is determined solely by the photo-cell; i.e., the Relay output is on whenever the photocell…

Hour Meter Timer (8 Pins)

LS8106-S, LS8106

LS8106 is a monolithic CMOS integrated circuit designed for driving electro-mechanical hour meters. It produces output pulses at regular intervals to advance the hour meter display. The first output pulse occurs between 3 to 4 seconds after application of the supply voltage. Thereafter the pulses occur at time intervals of 3.6 seconds for 10,000 hours display range or 36 seconds for 100,000 hours display range.
