The LS7213 is a monolithic 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 the Out2 outputs. Three inputs, D1, D2 and D3 select 1-of-8 scale factors, s. The delay, td is related to s by the express.
• Eight timing ranges
• Four modes
• RC controlled on-chip oscillator
• Power-On-Reset (POR)
• Reset input for delay abort
• Complementary outputs
• Delay-in-Progress Indicator output
• LS7213 (DIP), LS7213-S (SOIC) - See Figure 1 APPLICATIONS Time delay relays for HVAC equipment and industrial controls.
