ELM453 Overview
Key Specifications
Length: 13.589 mm
Description
The ELM452 and ELM453 devices each consist of an infrared emitting diode, optically coupled to a high speed photo detector transistor. A separate connection for the photodiode bias and output-transistor collector increase the speed by several orders of magnitude over conventional phototransistor couplers by reducing the base-collector capacitance of the input transistor.
Key Features
- High speed 1Mbit/s
- High isolation voltage between input and output (Viso=3750 Vrms )
- High CMR 15KV/us at VCM=1500V (ELM453)
- Guaranteed performance from 0° C to 70° C
- Wide operating temperature range of -40° C to 85° C
