Description
These diode-transistor optocouplers use an insulating layer
between a LED and an integrated photodetector to provide
electrical insulation between input and output. Separate
connections for the photodiode bias and output-transistor
collector increase the speed up to a hundred times that of a
conventional phototransistor coupler by reducing the
base-collector capacitance.
These single channel optocoup-lers are available in 8-pin
DIP, SO-8, and Widebody package configurations.
The 6N135, HCPL-0500, and HCNW135 are for use in
TTL/CMOS, TTL/LSTTL or wide-bandwidth analog
applications. Current transfer ratio (CTR) for these devices
is 7% minimum at IF = 16 mA.
The 6N136, HCPL-2502, HCPL-0501, and HCNW136 are
designed for high-speed TTL/TTL applications. A standard
16-mA TTL sink current through the input LED will provide
enough output current for 1 TTL load and a 5.6 k pull-up
resistor. CTR for these devices is 19% minimum at
IF=16mA.
