Fairchild Semiconductor extends 3.3V optocoupler selection for high-speed industrial apps

With the introduction of FODM8061 and FODM8071, Fairchild Semiconductor has expanded its 3.3V optocoupler products to offer high isolation, strong noise immunity and high performance. The FODM8061 with open collector output and the FODM8071 with logic gate output suitable for industrial applications operate in harsh environments where electrical signals are processed in the presence of transients or continuous high voltages.

The key features of these optocoupler devices are,

High common mode noise immunity (CMR) of 20kV/µs minimum
Operating voltage range of 3.3V to 5V
Offers logic-level translation
Certified by UL1577 and IEC60747-5-2 standards

Fairchild says that Isolators, such as optocouplers, are instrumental in avoiding downtime from unexpected errors due to noise. These optocouplers create robust systems with low transmission error rates, low system failure rates and high reliability over extended periods of time.

Operating temperature range: -40º to +110º C

Package: 5-pin SO package
Price:
FODM8061: Each $ 1.19 for 1k pieces
FODM8071: Each $1.55 for 1k pieces
Availability: Now in samples
