MAX22421CASA+ General Description

The MAX22_2_ are a family of 2-channel reinforced ultra-low-power digital isolators. The MAX22_2_ consume ultra-low power not only in DC but also across the entire operating speed range up to 10Mbps. The family offers two unidirectional channel configurations to accommodate any 2-channel design.

Key Features

Ultra-Low Power Consumption
- 11.4µA per Channel at DC with V_DD = 3.3V
- 15.4µA per Channel at 100kbps with V_DD = 3.3V
- 54.7µA per Channel at 1Mbps with V_DD = 3.3V
Wide Supply Range Supports from 1.71V to 5.5V
Reinforced Galvanic Isolation for Digital Signals
- 8-NSOIC with 4mm Creepage and Clearance Withstands 3kV_RMS for 60s (VISO) and Continuously Withstands 445V_{RMS (VIOWM)}
- 8-WSOIC with 8mm Creepage and Clearance Withstands 5kV_RMS for 60s (VISO) and Continuously Withstands 848VRMS (VIOWM)
- Withstands ±10kV Surge Between GNDA and GNDB with 1.2/50µs Waveform
- High CMTI (200kV/µs, min)
Low Propagation Delay and Low Jitter
- Maximum Data Rate Up to 10Mbps
- Low Propagation Delay 51ns (typ) at V_DD = 3.3V
- Clock Jitter RMS 15.4ps (typ)
Safety Regulatory Approvals
