CTM452, CTM453 5 Pin Mini-Flat
1 Mbit/s High Speed Transistor Coupler
Features
High speed 1Mbit/s High isolation voltage between input and output
(Viso=3750 Vrms ) Guaranteed CTR performance from 0°C to 70°C Wide operating temperature range of -55°C to
100°C Green Package Regulatory Approvals
UL - UL1577 (E364000) VDE - EN60747-5-5(VDE0884-5) CQC – GB4943.1, GB8898 IEC60065, IEC60950
Description
The CTM452 and CTM453 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. The devices are packaged in a Mini-Flat package .
Applications
Line receivers Telecommunication equipment Feedback loop in switch-mode power supplies Home appliances High speed logic ground isolation
