Features
• 1 µm CMOS IC Technology
• Compatibility with All +5 V
CMOS and TTL Logic
Families
• No External Components
Required for Logic Interface
Description
compatible and is controlled by
the output enable pin, VOE.
The HCPL-7100/7101 optocoup-
ler combines the latest CMOS IC
technology, a new high-speed
high-efficiency AlGaAs LED, and
an optimized light coupling system
to achieve outstanding perfor-
mance with very low power
consumption. It requires only two
bypass capacitors for complete
CMOS/TTL compatibility.
The HCPL-7100/7101 consumes
very little power, due to the
CMOS IC technology and the light
coupling system. The entire
optocoupler typically uses only 10
mA of supply current, including
the LED current.
• High Speed: 15 MBd
(HCPL-7100) and 50 MBd
(HCPL-7101) Guaranteed
World-wide safety approval and
3750 Vac/1 minute dielectric with-
stand is achieved with our
patented “light-pipe” optocoupler
packaging technology.
• Low Power Consumption
• Safety Approvals
UL 1577 (3750 Vac/1 Min)
VDE 0884 (VIORM = 848
V peak)
CSA
• 3-State Output
• 3750 Vac/1 Minute Dielectric
Withstand
• High Common Mode
Transient Immunity
Basic building blocks of the
HCPL-7100/7101 are a CMOS
LED driver IC, an AlGaAs LED,
and a CMOS detector IC. A CMOS
or TTL logic input signal controls
the LED driver IC which supplies
current to the LED. The detector
IC incorporates an integrated
photodiode, a high-speed trans-
impedance amplifier and a voltage
comparator with hysteresis. The
3-state output is CMOS and TTL
The HCPL-7100/7101 provides he
user with an easy-to-use CMOS or
TTL compatible optocoupler
ideally suited for a variety of
applications where high speed
and low power consumption are
desired.
