Truth Table (Positive Logic) Input Output On (H) L Off (L) H NOTE: Broadcom The connection of a 0.1 µF bypass capacitor between VCC and GND is recommended. Hermetically Sealed, Transistor Output Optocouplers for Analog and Digital Applications Each channel contains a GaAsP light emitting diode that is optically coupled to an integrated photon detector. Separate connections for the photodiodes and output transistor collectors improve the speed up to one-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 at IF = 16 mA. The 18V VCC capability enables 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. 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 the 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.
