Data Sheet
Description
The ACPL-K370 and ACPL-K376 are voltage/current
threshold detection optocouplers. The ACPL-K376 is a low-
current version of the ACPL-K370. To obtain lower current
operation, the ACPL-K376 uses a high-efficiency AlGaAs
LED which has higher light output at lower drive currents.
Both devices have a threshold sensing input buffer IC
that allows threshold levels to be set by a single external
resistor over a wide range of input voltages.
The input buffer has several performance enhancing
features: hysteresis for extra noise immunity and
switching immunity, a diode bridge for easy use with AC
input signals, and internal clamping diodes to protect the
buffer and LED from over-voltage and over-current tran-
sients. Because threshold sensing is done prior to driving
the LED, variations in optical coupling from the LED to the
detector will not effect the threshold levels.
The ACPL-K370 input buffer IC has a nominal turn-on
threshold of 3.8 V(VTH+) and 2.77 mA (ITH+). The buffer
IC for the ACPL-K376 is designed for lower input current.
The nominal turn-on threshold for the ACPL-K376 is 3.8 V
(VTH+) and 1.32 mA (ITH+), which reduces power dissipa-
tion by 52%.
The high-gain output stage features an open-collector
output for both TTL compatible saturation voltages and
CMOS compatible breakdown voltages.
By combining many unique functions in a single package, the
ACPL-K370 and ACPL-K376 are ideal components for indus-
trial control computer input boards and other applications
where a predetermined input threshold level is needed.
