TOSHIBA PHOTOCOUPLER IRED & PHOTO IC
TLP553
Low input current line receiver Telephone ring detector Current loop receiver Interfaces for computer, measurement equipment and control equipment Data transfer between circuits of different potentials
TLP553
Unit: mm
TLP553 is a Darlington 8-pin DIP photocoupler, which consists of an infrared emitting diode a photodiode and a high-gain transistor integrated into a detector chip.
As it uses a high-speed, high-gain detector element, TLP553 is ideal for applications which require low-input current and high-speed data transmission.
• Current transfer ratio: 400% (min) @IF = 0.5 mA
• Operating temperature: 0 to 70°C (guaranteed)
• Switching speed:
• Isolation voltage: • UL-recognized:
tpHL = 2 μs, tpLH = 4 μs (typ.) @RL = 4.7 kΩ, IF = 0.
