ELM742xxC CMOS Low power voltage comparator ■General description ELM742xxC is a low voltage and low power comparator which can input and output signals in full range of Vdd to Vss. ELM742xxC can operate with single power source and low voltage supply (operating voltage range : VDD≥1.0V) condition. ELM742xxC provides 2 kinds of output style: N-ch opendrain and CMOS output. ■Features ■Application • Low voltage operation : Vdd≥1.0V • Low current consumption : Typ.1μA(Vdd=3.6V, Vout=”Low”) Typ.0.6μA(Vdd=3.6V, Vout=”High”) • Operating voltage range : 1.0V≤Vdd≤7.0V • Input voltage range : Vss to Vdd • Output stage : N-ch open drain or CMOS output • Package : SOT-25, SC-70-5(SOT-353) • Battery-operated devices • Micropower signal processing • Low voltage analog circuits ■Maximum absolute ratings Parameter Power supply voltage Input voltage Output voltage Symbol Vdd Vin Limit Vss-0.3 to +8.0 Vss-0.3 to Vdd+0.3 N-ch : Vss-0.3 to +8.0 CMOS : Vss-0.3 to Vdd+0.3 300 (SOT-25) 150 (SC-70-5)(SOT-353) -20 to +70 -55 to +125 Vout Power dissipation Pd Operating temperature Storage temperature Top Tstg Unit V V V mW °C °C ■Selection guide ELM742xxC-x Symbol a Output form b Package c Product version d Taping direction N : N-ch open drain C : CMOS B : SOT-25 C : SC-70-5(SOT-353) C(fixed) S: Refer to PKG file N: Refer to PKG file 4- 1 ELM742 x x C - x ↑ ↑↑ ↑ a b c d Rev.1.1 ELM742xxC CMOS Low power voltage comparator ■Pin configuration TOP VIEW - 1 Pin No. 1 2 3 4 5 4 5 + 3 2 Pin name INVDD IN+ OUT VSS ■Electrical characteristics Parameter Power supply voltage Common-mode input voltage Input offset voltage Input current Output current Current consumption Response time Symbol Vdd Vicr Vio-1 Vio-2 Vio-3 Iin IoutN-1 IoutN-2 IoutP-1 IoutP-2 Iss-1 Iss-2 tHL tLH Condition Vdd=1.0 to 7.0V Vdd=1.0V, Vicr=0.5V Vdd=3.6V, Vicr=1.8V Vdd=7.0V, Vicr=3.5V Vdd=1.0 to 7.0V Vdd=1.0V, Vout=0.4V Vdd=1.5V, Vout=0.4V Vdd=1.0V, Vout=0.6V Vdd=1.5V, Vout=1.1V Vdd=3.6V, Vout:"L" Vdd=7.0V, Vout:"L" Vdd=3.6V Vdd=3.6V Min. 1.0 Vss -8 -8 -8 Typ. 0.4 4.0 0.06 0.35 1.5 6.0 0.15 0.45 2.0 2.2 30 30 Vss=0V, Top=25°C Max.
