LM393

Voltage Comparator LM393 Voltage Comparator General Description • The TCI LM393 consist of two independent voltage comparator, designed specifically to operate from a single power supply over a wide voltage range. • The LM393 is available in standard DIP-8, SOP-8 and TSSOP-8 packages. . DIP-8 SOP-8 TSSOP-8 Features • Single or dual supply operation • Wide operating supply range (VCC=2V ~ 36V or ±1 ~ ±18V) • • • • • Applications • • • • • Battery Charger Cordless Telephone Switching Power Supply PC Motherboard Communication Equipment Input common-mode voltage includes ground Low supply current drain ICC=0.8mA (Typical) Low input bias current IBIAS=25nA (Typical) Output compatible with TTL, DTL, and CMOS logic system RoHS Compliance Ordering Information TAITRON COMPONENTS INCORPORATED www.taitroncomponents.com Tel: Fax: (800)-TAITRON (800)-824-8766 (800)-TAITFAX (800)-824-8329 (661)-257-6060 (661)-257-6415 Rev.
