Description
The HCPL-0738 is a dual-channel 15 MBd CMOS
optocoupler in SOIC-8 package. The HCPL-0738
optocoupler utilizes the latest CMOS IC technol-
ogy to achieve out-standing performance with very low
power consumption. Basic building blocks of HCPL-0738
are high speed LEDs and CMOS detector ICs. Avago also
oers the same performance in the single channel ver-
sion, HCPL-0708. Each detector incorporates an integrated
photodiode, a high speed transimpedance amplier, and
a voltage comparator with an output driver.
