LOW INPUT CURRENT
LOGIC GATE OPTOCOUPLERS
FOD2200
DESCRIPTION
The FOD2200 is an optically coupled logic gate that combine an AlGaAs LED
and an integrated high gain photo detector. The detector has a three state
output stage and has a detector threshold with hysteresis. The three state
output eliminates the need for a pullup resistor and allows for direct drive of
data busses. The hysteresis provides differential mode noise immunity and
eliminates the potential for output signal chatter.
The Electrical and Switching Characteristics of the FOD2200 are guaranteed
over the temperature range of 0°C to 85°C and a VCC range of 4.5 volts to 20
volts. Low IF and wide VCC range allow compatibility with TTL, LSTTL, and
CMOS logic and result in lower power consumption compared to other high
speed optocouplers. Logic signals are transmitted with a maximum propaga-
tion delay of 300 nsec. The FOD2200 is useful for isolating high speed logic
interfaces, buffering of input and output lines, and implementing isolated line
receivers in high noise environments.
