LM293M/TR

LM293 DUAL DIFFERENTIAL COMPARATOR „ DESCRIPTION The HGsemi LM293 consists of two independent voltage comparators, designed specifically to operate from a single power supply over a wide voltage range. SOP-8 „ FEATURES * Single or dual supply operation. * Wide operating supply range (VCC=2V ~ 36V or ±1 ~ ±18V) * 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. „ DIP-8 PIN DESCRIPTION http:www.hgsemi.com.cn OUT 1 1 8 IN 1(-) 2 7 IN 1(+) 3 6 IN 2(-) GND 4 5 IN 2(+) 1 Vcc OUT 2 2018 MAY LM293 „ „ BLOCK DIAGRAM ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage Differential Input Voltage Input Voltage SYMBOL VCC VI(DIFF) VIN DIP-8 SOP-8 Power Dissipation PD RATINGS ±18 or 36 UNIT V V V mW mW 36 -0.3 ~ +36 600 420 Operating Temperature Range TOPR -20 ~ +85 °C Storage Temperature Range TSTG -65 ~ +150 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
