STR83145 LATCHED / UNIVERSAL INPUT-VOLTAGE SWITCHES

STR83145 AND STR84145 INTERIM ISSUE (subject to change without notice) August 16, 1994 Data Sheet 28190 LATCHED, UNIVERSAL INPUT-VOLTAGE SWITCHES Intended for power supplies with universal inputs (85 V to 265 V rms), the STR83145 and STR84145 latched, universal input-voltage switches incorporate timing, control, and drive circuitry with a highcurrent triac (bidirectional triode thyristor) switch. Each device senses the applied ac line potential and automatically switches the rectifier and asso.
