Be careful not to confuse the with the LM1458 or MC1458 . While they share the "1458" number, the LM1458 is a Dual Operational Amplifier and does not provide optical isolation.
, allowing for seamless integration into both 3.3V and 5V logic systems. Low Drive Power : Requires low forward current ( cap I sub cap F 1458 optocoupler datasheet
: Available in an 8-pin hermetically sealed package (SOP-8 or similar), protecting internal components from environmental factors. Electrical Specifications Typical/Max Value Forward Current ( IFcap I sub cap F ) 20 mA (Max) Output Current ( ICcap I sub cap C ) Operating Temperature -55°C to +100°C Propagation Delay 35 ns at 10 kHz Common Applications Be careful not to confuse the with the LM1458 or MC1458
If the user needs an optocoupler and mistakenly searched for "1458," here are correct alternatives: Low Drive Power : Requires low forward current
