GENERAL DESCRIPTION

The ALD4301A/ALD4301 is a monolithic high performance quad voltage comparator built with advanced silicon gate CMOS technology. It features very high typical input impedance of 1012?; low input bias current of 10pA; fast response time of 300ns; very low power dissipation of 55μA per comparator; high output drive and single (+5V) or dual (±5V) power supply operation.

FEATURES

? Fanout of 30LS TTL loads

? Low supply current of 55μA/comparator typical

? Pinout/Functional equivalent to LM393 types

? Extremely low input bias currents -- typically 10pA

? Virtually eliminates source impedance effects

? Low operating supply voltage of 3V to 10V

? Single (+5V) and dual supply (±5V) operation

? High speed for both large signal and low level signals -- 300ns typical for TTL inputs

? CMOS, NMOS and TTL compatible

? Wired-OR open drain outputs

? High output sinking current -- typically 60mA

? Low supply current spikes

? High gain
