Agilent HCPL-0738
High Speed CMOS Optocoupler
Data Sheet
Features
• 15 ns typical pulse width
distortion
• 40 ns maximum prop. delay skew
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.
• 20 ns typical prop. delay
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.
• High speed: 15 MBd
• + 5 V CMOS compatibility
• 10 kV/µS minimum common mode
rejection
• –40 to 100˚C temperature range
• Safety and regulatory approvals
– UL recognized (2500 V rms for
1 minute per UL 1577)
– CSA component acceptance
notice #5.
– VDE 0884 (TUV) approved for
HCPL-0738 Option 060
Applications
• PDP (plasma display panel)
• Digital field bus isolation:
DeviceNet, SDS, Profibus
• Multiplexed data transmission
• Computer peripheral interface
• Microprocessor system interface
• DC/DC converter
