HCPL-0700, HCPL-0701, HCNW138, HCNW139,
6N139, 6N138,
Low Input Current, High Gain Optocouplers
Data Sheet
Description
These high gain series couplers use a Light Emitting
Diode and an integrated high gain photodetec tor to
provide extremely high current transfer ratio between
input and output. Separate pins for the photodiode
and output stage result in TTL compatible saturation
voltages and high speed operation. Where desired the
V
CC
and V
O
terminals may be tied together to achieve
conven tional photodarlington operation. A base
access terminal allows a gain bandwidth adjustment to
be made.
The 6N139, HCPL-0701, and HCNW139 are for use in
CMOS, LSTTL or other low power appli ca tions. A 400%
minimum current transfer ratio is guaranteed over 0 to 70°C
operating range for only 0.5 mA of LED current.
The 6N138, HCPL-0700, and HCNW138 are designed for
use mainly in TTL applications. Current Transfer Ratio
(CTR) is 300% minimum over 0 to 70°C for an LED current
of 1.6 mA (1 TTL Unit load ). A 300% minimum CTR
enables operation with 1 TTL Load using a 2.2 kΩ
pull-up resistor.
