ISO7421EQDWRQ1

汽车类双通道 1/1、50Mbps 数字隔离器 16-SOIC -40 to 125

The ISO7421E-Q1 provides double galvanic isolation of up to 2.5 KVrms for 1 minute per UL. This digital isolator has two isolation channels in a bi-directional configuration. Each isolation channel has a logic input and output buffer separated by a silicon oxide SiO2 insulation barrier. Used in conjunction with isolated power supplies, these devices prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry.

The devices have TTL input thresholds and require two supply voltages, 3.3 V or 5 V, or any combination. All inputs are 5-V tolerant when supplied from a 3.3-V supply.

**Note:** The ISO7421E-Q1 is specified for signaling rates up to 50 Mbps. Due to their fast response time, under most cases, these devices will also transmit data with much shorter pulse widths. Designers should add external filtering to remove spurious signals with input pulse duration < 20 ns if desired.
