It supports a data rate of 1 Mbps across its two unidirectional channels, with both channels configured as inputs on Side 1 and outputs on Side 2.
The 2500 Vrms isolation rating covers basic insulation requirements for industrial equipment per IEC 60747-5-5. Propagation delay is 475 ns max (both tpLH and tpHL), with pulse width distortion limited to 14 ns max — tight enough for most 1 Mbps SPI and UART links without bit errors.
The ISO7220AD is a Texas Instruments general-purpose digital isolator with capacitive coupling, two unidirectional channels, a 1 Mbps data rate, and 2500 Vrms isolation in an SOIC-8 package.
The ISO7220AD supports a maximum data rate of 1 Mbps.
Within the ISO7220 family, pin-compatible variants exist with different channel counts and data rates, but no direct second-source alternate from another manufacturer is recorded. For a higher-speed alternative, consider the ISO7221 series which offers the same pinout at higher data rates.
