16V CMOS analogue comparators boost efficiency, speed & reliability
Compatible with the previous-generation ICs, the TSX393, TSX339, TSX3702, and TSX3704 further extend the performance and efficiency advantages of ST’s CMOS devices over bipolar comparators. With their wide single-supply voltage range of 2.7 – 16V, these comparators can operate from the standard voltages used in a wide variety of applications, including industrial or automotive equipment. The devices are specified over the in temperature range -40°C to 125°C, and have higher ESD capability than their predecessors thereby enhancing the reliability of sensing and control systems in harsh environments.
TSX393 and TSX339 integrate two and four comparators respectively, and feature open-drain outputs that can help simplify circuit design where OR-ing or level shifting are required. The dual TSX3702 and quad TSX3704 have push-pull outputs for reliable signalling without pull-ups. Output-drive capability of up to 20 mA allows direct connection to a variety of analog or digital loads.
ST is also introducing smaller package styles that ease design-in and simplify board layout and routing. The TSX393 and TSX3702 are available in a 2 x 2 mm DFN8 in addition to SO-8, Mini-SO8, and TSSOP-8 packages. The TSX339 and TSX3704 can be ordered as a 3 x 3 mm QFN16, as well as SO-14 and TSSOP-14. ST is in the process of qualifying the SO-8 and TSSOP-14 devices according to AEC-Q100.
TSX-series comparators are priced from $0.395 for the TSX393 or TSX3702 (dual), $0.527 for the TSX3704 (quad), and $0.546 for the TSX339 (quad) (all 1000).
