Precision Voltage Comparators See GENERAL DESCRIPTION FEATURES The pPC271/311 are voltage comparators that have © Operate from single 5 V supply input currents more than a hundred times lower than @ Maximum input current: 250 nA device like conventional standard type of 710. It is also @ Maximum offset current: 50 nA designed to operate over a wide range of supply voltages: © Fast transient response: 200 ns TYP. from £15 V op amp supplies down to the single 5V @ 1M311 Direct Replacement supply used for IC logic. Its output is.compatible with HNIL, DTL and TTL as well as MOS circuits, Two kinds of ICs are available according to reliabi- lity, the wPC271 for industry, the pPC311 for com mercial, EQUIVALENT CIRCUIT ORDERING INFORMATION e ” uPC271ED Ha fa LJ | 2% a, G, LU es B pin Ceramic DIF | al tn a (Dust In-Line Package) f | | c.
