AS “АLFA RPAR” AS527 Riga, Latvia www.alfarzpp.lv; alfa@alfarzpp.lv Voltage comparator Block diagram AS527
FEATURES
Pin-to-pin compatible with industry standard NE527 15 ns propagation delay Complementary output gates TTL or ECL compatible outputs Wide common-mode and differential voltage range Typical gain of 5000
DESCRIPTION
The NE527 is a high-speed analog voltage comparator which mates Schottky diode technology with the conventional linear process. This allows simultaneous fabrication of high speed TTL gates with a precision linear amplifier on a single monolithic chip.
