Hermetically Sealed Optocoupler, AC/DC to Logic Interface
The HCPL-5760 is a single channel hermetically sealed voltage/current threshold detection optocoupler in an 8-Pin ceramic DIP package with gold plated leads. Solder dipped leads and various lead form options are also available. See the datasheet for details.
The product is capable of operation and storage over the full military temperature range and may also be purchased with full MIL-PRF-38534 Class H or K level testing or from the DSCC Standard Microcircuit Drawing (SMD) 5962-89477.
The HCPL-5760 is manufactured and tested on a MIL-PRF-38534 certified line and Class H and K versions are included in the DSCC Qualified Manufacturers List, QML-38534 for Hybrid Microcircuits. Each device contains a light emitting diode, a threshold sensing input buffer IC, and a high gain photon detector to provide an optocoupler which permits adjustable external threshold levels. The input buffer circuit has a nominal turn on threshold of 2.5 mA (ITH ) and 3.6 volts (VTH ). The addition of one or more external attenuation resistors permits the use of this device over a wide range of input voltages and currents. Threshold sensing prior to the LED and detector elements minimizes effects of any variation in optical coupling. Hysteresis is also provided in the buffer for extra noise immunity and switching stability.
The buffer circuit is designed with internal clamping diodes to protect the circuitry and LED from a wide range of over-current transients while the diode bridge enables easy use with ac voltage input.
These units combine several unique functions in a single package, providing the user with an ideal component for computer input boards and other applications where a predetermined input threshold optocoupler level is desirable.
The high gain output stage features an open collector output providing both TTL compatible saturation voltages and CMOS compatible breakdown voltages.
