1 standard ics dual comparators ba10393 / ba10393f / ba10393n the ba10393, ba10393f, and ba10393n are dual comparators with open-collector output which allows wired or connections. the operating power supply voltage ranges from 2 to 36v for a single power supply and 1 to 18v for a dual power supply. the packages are as follows: dip 8-pin (ba10393), sop 8-pin (ba10393f), and sip 8-pin (ba10393n). features block diagram 1 2 3 4 8 7 6 5 1ch + 2ch + v cc out2 ?in2 + in2 out1 ?in1 + in1 v ee 1 1ch + v cc out2 ?in2 + in2 out1 ?in1 + in1 v ee 2 3 4 5 6 7 8 2ch + ba10393 / ba10393f ba10393n 1) wide operating voltage range. (single power supply: 2 to 36v, dual power supply: 1 to 18v) 2) low current dissipation. (0.4ma typ. at v cc = 5v) 3) low input offset voltage. (25na typ. at v cc = 5v) and low input offset voltage. (typically ?.0mv at v cc = 5v) 4) wide common-mode input voltage. (0 to v cc ?1.5v) 5) open collector output. 6) compatible with 393 comparators from other manu- facturers.
