FOD2200 Datasheet | Fairchild Semiconductor

DESCRIPTION The FOD2200 is an optically coupled logic gate that bine an Al Ga As 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 patibility with TTL, LSTTL, and CMOS logic and result in lower power consumption pared to other high speed optocouplers. Logic signals are transmitted with a maximum propagation 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. 8 1 8 1 8 1 FEATURES - 1 k V/µs Minimum mon Mode Rejection - patible with LSTTL, TTL, and CMOS Logic - Wide VCC Range (4.5 to 20 V) - 2.5 Mbd Guaranteed over Temperature - Low Input Current (1.6 m A) - Three State Output (No Pullup Resistor Required) - Guaranteed Performance from 0°C to 85°C - Hysteresis - Safety Approvals Pending - UL, CSA, VDE - VISO = 5k VRMS APPLICATION - - - - - - - Isolation of High Speed Logic Systems puter-Peripheral Interfaces Microprocessor System Interfaces Ground Loop Elimination Pulse Transformer Replacement Isolated Buss Driver High Speed Line Receiver NC 1 ANODE 2 CATHODE 3 NC 4 8 VCC 7 VO 6 VE 5 GND SHIELD Schematic ICC 8 IF + VF - 2 IE 3 SHIELD 6 5 IO 7 VCC VO VE GND TRUTH TABLE (Positive Logic) LED On Off On Off Enable H H L L Output Z Z H L © 2004 Fairchild Semiconductor Corporation Page 1 of 14 7/7/04 LOW INPUT CURRENT LOGIC GATE OPTOCOUPLERS ABSOLUTE MAXIMUM RATINGS (TA = 25°C unless otherwise specified) Parameter Storage...
