High Noise Immunity, 5V, 10Mbit/sec Logic Gate Output

(Open Collector) Optocoupler

Features

Description

■ High Noise Immunity characterized by common mode

The FODM611 is a 5V high-speed logic gate output

(open collector) optocoupler, which supports isolated

communications allowing digital signals to communicate

between systems without conducting ground loops or

hazardous voltages. It utilizes Fairchild’s patented

transient immunity (CMTi)

– 20kV/µs Minimum CMTi

■ High Speed

– 10Mbit/sec Date Rate (NRZ)

– 100ns max. Propagation Delay

– 35ns max. Pulse Width Distortion

– 40ns max. Propagation Delay Skew

■ -40 to +85°C temperature range

■ Safety and regulatory approvals

coplanar packaging technology, Optoplanar , and

optimized IC design to achieve high noise immunity,

characterized by high common mode transient immunity

specifications.

This optocoupler consists of an AlGaAS LED at the

input, optically coupled to a high speed integrated photo-

detector logic gate. The output of the detector IC is an

open collector schottky-clamped transistor. The coupled

parameters are guaranteed over the wide temperature

range of -40°C to +85°C. A maximum input signal of

5mA will provide a minimum output sink current of 13mA

(fan out of 8).

– UL1577, 3750 VAC

for 1 min.

RMS

– IEC60747-5-2 (pending approval)

Applications

■ Microprocessor system interface

– SPI, I C
