No. 7980 APPLICATIONS * General Telecom Switching - On/off-hook Switching - Dial Pulse - Ring Current Detection - Loop Current Sensing DESCRIPTION The LH1539 telecom switch consists of an optically isolated solid state relay (SSR) Form A and a bidirectional input optocoupler in a single 8-pin package. The SSR is ideal for switchhook and dial-pulse switching while the optocoupler performs ring detect and loop current sensing functions. Both the SSR and optocoupler provide 5300 VRMS of input-to-output isolation voltage. The SSR is integrated on a monolithic receptor die using smart power technology. The SSR features low ONresistance, high breakdown voltage, and current-limit circuitry that protects the relay from telephone line induced lightning surges. The optocoupler provides bidirectional current sensing via two antiparallel GaAs infrared emitting diodes. Very high current transfer ratio (CTR) is achieved by coupling to a photodarlington transistor. This high CTR allows the user to minimize the size of the ring detector capacitor. .268 (6.81) .255 (6.48) Package Dimensions in Inches (mm) DIP pin one ID 4 .268 (6.81) .255 (6.48) 5 6 7 8 3 2 1 8 7 6 5 .390 (9.91) .379 (9.63) .045 (1.14) .030 (0.76) 4 typ. .150 (3.81) .130 (3.30) .050 (1.27) .022 (.56) .018 (.46) .035 (.89) .020 (.51) .100 (2.54) typ. .031 (0.79) 1 2 3 4 .300 (7.62) typ. 10 3-9 .012 (.30) .008 (.20) .250 (6.35) .230 (5.84) .130 (3.30) .110 (2.79) SMD Pin one I.D. .390 (9.91) .379 (9.63) .031 (.79) typ. .150 (3.81) .130 (3.30) .395 (10.03) .375 (9.52) .312 (7.80) .298 (7.52) 3 to 7 .045 (1.14) .030 (0.78) Radius 4 typ. .050 (1.27) typ. .008 (.25) .004 (.10) .040 (1.02) .020 (.51) .100 (2.54) typ. 10 .315 (8.00) typ. .010 (2.54) typ.
