Description
These high gain series couplers use a Light Emitting
Diode and an integrated high gain photodetector 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
conventional photodarlington operation. A base
access terminal allows a gain bandwidth adjustment to
be made.
The 6N139, HCPL-0701, and CNW139 are for use in CMOS,
LSTTL or other low power applications. A 400% mini-
mum 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 (1TTL Unit load ). A 300% minimum CTR
enables operation with 1 TTL Load using a 2.2 kΩ
pull-up resistor.
