The input circuit features a high-efficiency Gallium Arsenide (GaAs) Light Emitting Diode (LED). When a forward current ( IFcap I sub cap F
Whether you are building a smart home switch or a power supply, the A1458 is a reliable, cost-effective component to keep in your parts bin.
As an isolator for PWM signals in inverter circuits managing speed and torque.
Features an integrated insulating layer to provide robust electrical isolation between input and output. Output Type: Typically features an open collector output
The A1458 is an optically coupled isolator consisting of a GaAsP LED and an integrated high-gain photodetector. It is designed for high-speed logic gate isolation and is commonly used in industrial and telecommunication environments to provide galvanic isolation while maintaining signal integrity. Specification Speed (Propagation Delay) 8 ns max (tPHL/tPLH) Isolation Voltage Supply Voltage (VCC) 3.0V to 5.5V Common Mode Rejection (CMR) 50 kV/µs minimum Current Consumption (ICC) 1.2 mA max (Low power) Operating Temperature -40°C to +105°C (Extended range) Package Types 8-Pin DIP, SOIC-8 / SOP-8 Core Features
When connecting two pieces of equipment that may have different ground potentials (e.g., a computer and an industrial sensor), a direct connection can create a ground loop, leading to erratic data or damage. Placing an A1458 optocoupler between them breaks the ground loop while allowing data to pass, thanks to its excellent noise immunity.
