Description
Features
High current transfer ratio – 2000% typical (4500 %
typical for HCNW139/138)
Low input current requirements – 0.5 mA
TTL compatible output – 0.1V VOL typical
Performance guaranteed over temperature 0°C
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
to70°C
V
and VO terminals may be tied together to achieve
CC
Base access allows gain bandwidth adjustment
High output current – 60mA
Safetyapproval
UL recognized – 3750 V rms for 1minute and 5000 V
rms* for 1minute per UL 1577
CSA approved
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 0to 70°C
operating range for only 0.5 mA of LED current.
IEC/EN/DIN EN 60747-5-2 approved with VIORM = 1414
Vpeak for HCNW139 and HCNW138
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.
