Description:

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, D2, and D3 select 1-of-8 scale factors, s. The delay, td, is related to s by the expression, td = s/frc, where frc is the frequency at the RC input produced by an internal oscillator. An external resistor-capacitor pair connected to the RC pin controls the oscillator frequency. There are four modes of operation selected by inputs A and B: On-Delay (OND), Off-Delay (OFD), Dual-Delay (DLD), and One-Shot (OST). These modes are described in detail in the datasheet.
