1 , Features: TTL compatible output 16 KV isolation 5 kbits/s transfer rate t PHL t PLH 5 ns Creepage path:.97 (24.64 mm) Air path:.97 (24.64 mm) UL recognized file No. E5873* Product Photo Here Description: The is a high voltage isolator that consists of a GaAIAs LED with a peak wavelength of 89 nm, which is coupled with a unique integrated circuit detector. Photons are collected in the detector by a photodiode and amplified by a highgain linear amplifier that drives a Schottky clamped open collector output transistor. The circuit is temperature, current and voltage compensated. Propagation delay times are matched within 5 nanoseconds over the entire temperature range for timing purposes (Δ T P = t PHL t PLH ). *UL recognition is for 5833 VAC for one minute. This design produces maximum DC and AC current isolation between the input and output, while providing TTL/LSTTL circuit compatibility. The is a high voltage isolator with a digital output that is capable of high speed data transmission. The input of the consists of a highefficiency GaAlAs LED with a peak wavelength of 85 nm, which is optically coupled to the output optical IC. A photodiode in the output IC detects the incoming modulated light and converts it to a proportionate current. This current is fed into a highgain linear amplifier which is temperature, current and voltage compensated. The result is a highly stable digital output with an open collector inverter configuration. This device produces DC and AC voltage isolation between the input and output circuitry, while providing TTL signal integrity.
