improve the speed to a hundred times that of a conventional phototransistor optocoupler by reducing the base-collector capacitance. These devices are suitable for wide bandwidth analog applications, as well as for interfacing TTL to LSTTL or CMOS. Current Transfer Ratio (CTR) is 9% minimum = 16 mA. The 18 V VCC


These units are single, dual and quad channel, hermetically sealed optocouplers. The products are capable of operation and storage over the full military temperature range and can be purchased as either standard product or with full MIL-PRF-38534 Class Level or K testing or from the appropriate DSCC Drawing. All devices are manufactured and tested a MIL-PRF-38534 certified line and are included in the DSCC Qualified Manufacturers List QML-38534 for Hybrid Microcircuits. Each channel contains a GaAsP light emitting diode which is optically coupled to an integrated photon detector. Separate connections for the photodiodes and output transistor collectors

The connection � F bypass capacitor between VCC and GND is recommended. CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD.

capability will enable the designer to interface any TTL family to CMOS. The availability of the base lead allows optimized gain/ bandwidth adjustment in analog applications. The shallow depth of the IC photodiode provides better radiation immunity than conventional phototransistor couplers. These products are also available with the transistor base node connected to improve common mode noise immunity and ESD susceptibility. In addition, higher CTR minimums are available by special request.

Package styles for these parts are 8 and 16 pin DIP through hole (case outlines P and E respectively), 16 pin DIP flat pack (case outline F), and leadless ceramic chip carrier (case outline 2). Devices may be purchased with a variety of lead bend and plating options, see Selection Guide Table for details. Standard Microcircuit Drawing (SMD) parts are available for each package and lead style. Because the same functional die (emitters and detectors) are used for each channel of each device

listed in this data sheet, absolute maximum ratings, recommended operating conditions, electrical specifications, and performance characteristics shown in the figures are identical for all parts. Occasional exceptions exist due to package variations and limitations and are as noted. Additionally, the same package assembly processes and materials are used in all devices. These similarities give justification for the use of data obtained from one part to represent other part's performance for die related reliability and certain limited radiation test results.
