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 technology to achieve out-

standing performance with very low

power consumption. Basic building

blocks of HCPL-0738 are high

speed LEDs and CMOS detector ICs.

Functional Diagram

Agilent also offers the same

performance in the single channel

version, HCPL-0708. Each

detector incorporates an

integrated photodiode, a high

speed transimpedance amplifier,

and a voltage comparator with an

output driver.
