Broadcom HCPL 9031 000E Digital Isolator with Industry Leading Speed and Excellent Transient Immunity
Product Overview
The Broadcom HCPL-90xx and HCPL-09xx series are high-speed CMOS digital isolators designed for robust performance and excellent transient immunity. Featuring industry-leading speed with a 100 Mbaud data rate, typical pulse width distortion of 2 ns, and typical propagation delay skew of 4 ns, these isolators are ideal for demanding digital communication applications. They offer 2500V RMS isolation and are available in various channel configurations (single, dual unidirectional/bidirectional, and quad) and package types (PDIP, Gull Wing, SOIC) to suit diverse design needs. Applications include digital fieldbus isolation, multiplexed data transmission, computer peripheral interfaces, and high-speed digital systems.

Application Information
Power Consumption: Power consumption is frequency-dependent and independent of mark-to-space ratio, due to edge-triggered pulse transmission across the isolation barrier. Approximate supply current per channel: I(Input) = 40(f/fmax)(1/4) mA, where fmax = 50 MHz.
Signal Status on Start-up and Shut Down: To avoid ambiguous output states, designers should consider including an initialization signal in the start-up circuit.
Bypassing and PC Board Layout: Use low ESR 47 nF ceramic capacitors for power supply decoupling, placed close to VDD pins. Ground planes for GND1 and GND2 are recommended for data rates above 10 Mb/s.
