521SA3

Universal voltage comparators 521СА3, 521СА301, Р554СА3А, Б521СА3-1, Н521СА3, К521СА301, К554СА301 and К554СА3 are general purpose voltage comparators (VC) with low input current and a wide input voltage range. They can work with a unipolar power supply as well, e.g. +5 V or -30 V. The comparator has two outputs: open collector and emitter. In this case the load can be connected to ground, and positive or negative supply rails. VCs are designed to be used in a wide range of applications. Advanced reliability VC 521СА301, 521СА3, Р554СА3А, and Б521СА3-1 are additionally marked with OCM index.

Notes:

* Absolute values of voltage at the microcircuits input terminals shall not exceed absolute values of power supply voltage.

Common-mode input voltage values are given for the power supply UCC=±16,5 V.

Comparator dissipated power shall not exceed 500mW. Dissipated power at ambient temperature above

75ОС is calculated according to the gollowing formula:

PTOT=500 – (tamb - 75ОС)/ RTh-r, где RTh-r=0,17ОС /mW - thermal rsistance (crystal - amb. medium).

Limit loads for products, starting with the letter "К" are not specified.
