Description
The HCPL-7601/11 is a low
input current version of the
HCPL-2601/11 and 6N137
(without enable). The optically
coupled gates combine an
AlGaAs high-efficiency light
emitting diode and an integrated
high gain photon detector to
create a low input current device
for low power applications. The
output of the detector IC is an
open collector Schottky-clamped
transistor. The internal shield
provides a guaranteed common
mode transient immunity
specification of 10,000 V/µs
(HCPL-7611).
This unique design provides
maximum ac and dc circuit
isolation while achieving CMOS
and TTL compatibility. The
optocoupler ac and dc
operational parameters are
guaranteed from -40°C to 85°C
with no derating required
allowing trouble free system
performance. This product is
suitable for high speed logic
interfacing, input/output
buffering, and applications that
require low input-current
switching levels.
The HCPL-7601/11 family offers
many features that are
especially beneficial to system
designers. The low input
current requirements and
guaranteed switching threshold
(2 mA max.) allows the LED to
be driven directly by any
standard high-speed CMOS
gate (e.g. 74HC/HCT). This will
simplify designs by eliminating
the need for special driver
circuits and result in lower part
counts and greater system
reliability while freeing up
valuable printed circuit board
space.
The wide current input range of
2 mA to 10 mA and guaranteed
ac and dc performance over a
wide temperature range will
also simplify designs. Low
supply current requirements
mean lower power dissipation
allowing for the use of a
smaller, less expensive power
supply. The high speed (10 Mbd
typ.) and low propagation delay
skew (T
psk
≤
40 ns guaranteed)
allow for easier design of high
speed parallel applications. The
world-wide regulatory approval
(UL/CSA/IEC/EN/DIN EN
60747-5-2) will facilitate the
acceptance of the end product in
international markets.
