Description

Product Overview

The ISO7762FDBQR from Texas Instruments is a high-speed, robust EMC, reinforced six-channel digital isolator in a 16-pin SSOP (DBQ) package. It provides 3000 Vrms isolation with 4 forward and 2 reverse channels, 100 Mbps data rate, and ultra-low propagation delay of 11 ns. The ‘F’ suffix indicates default output low when input power or signal is lost, making it ideal for failsafe communication bus isolation.

  • Excellent EMC: IEC 61000-4-2 ±8 kV contact ESD
  • UL 1577, VDE, CSA, TUV, CQC certified
  • 2.25 V to 5.5 V level translation across barrier

Applications

  • RS-485/RS-232/CAN bus isolation
  • Industrial automation and PLC systems
  • Motor drive isolation
  • Medical equipment isolation
  • Power supply feedback isolation

The Texas Instruments ISO7762FDBQR is a high-performance reinforced six-channel digital isolator providing 3000 Vrms isolation in a compact SSOP-16 package. It features four forward and two reverse channels, supporting bidirectional communication across the isolation barrier. With 100 Mbps data rate and 11 ns typical propagation delay, it is suited for high-speed digital interfaces. The device uses silicon dioxide (SiO2) as the isolation dielectric, offering robust electromagnetic compatibility including ±100 kV/µs CMTI and IEC 61000-4-2 ESD protection. The F suffix indicates default-low output state upon input power loss for failsafe system design.

The ISO7762F operates by encoding digital input signals into high-frequency pulses that are transmitted across a silicon dioxide (SiO2) isolation barrier via on-chip capacitors. The receiver side decodes these pulses back into the original digital logic levels. Each channel consists of an input buffer, RF modulator, isolation capacitors, RF demodulator, and output buffer. The 4/2 channel configuration allows bidirectional communication on a single package, making it efficient for half-duplex bus isolation. The default-low output (F variant) ensures that if the input side loses power, the outputs go to a defined low state, preventing undefined bus states in failsafe-critical applications like RS-485.
