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(V

IC for the ACPL-K376 is designed for lower input current.

The nominal turn-on threshold for the ACPL-K376 is 3.8 V

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.
