Data Sheet
HCPL-0720, HCPL-7720, HCPL-0721,
and HCPL-7721
40-ns Propagation Delay, CMOS Optocoupler
Description Features
Available in either an 8-pin DIP or SO-8 package style +5V CMOS compatibility
respectively, the Broadcom HCPL-772X or HCPL-072X
20-ns max propagation delay skew
optocouplers utilize the latest CMOS IC technology to
High speed: 25 MBd
achieve outstanding performance with very low power
40-ns max propagation delay
consumption. The HCPL-772X/072X require only two
10-kV/s minimum common mode rejection
bypass capacitors for complete CMOS compatability.
40 to +85C temperature range
Safety and regulatory approvals:
Basic building blocks of the HCPL-772X/072X are a CMOS
UL recognized
LED driver IC, a high-speed LED, and a CMOS detector IC.
3750 V for 1 min. per UL 1577
A CMOS logic input signal controls the LED driver IC, which
rms
supplies current to the LED. The detector IC incorporates an 5000 V for 1 min. per UL 1577 (for HCPL-772X
rms
option 020)
integrated photodiode, a high-speed transimpedance
amplifier, and a voltage comparator with an output driver. CSA component acceptance notice #5
