ISO7241C-Q

The ISO7241C-Q from Texas Instruments is a quad-channel digital isolator featuring multiple channel configurations. It utilizes TI's silicon dioxide (SiO2) isolation barrier to separate logic input and output buffers, effectively blocking high voltages and preventing noise currents from interfering with sensitive circuitry when used with isolated power supplies.

Key electrical specifications include a 4 kV isolation rating, 560 Vpeak VIORM, and support for signaling rates up to 150 Mbps. It also offers low channel-to-channel output skew (1 ns max) and low pulse-width distortion (2 ns max). The device operates with 3.3-V or 5-V supplies, and the input pins are 5-V tolerant regardless of the supply voltage.

Designed for demanding environments, the ISO7241C-Q is qualified for automotive applications and operates reliably within an ambient temperature range of -40°C to 125°C. Its high electromagnetic immunity ensures stable performance in noisy conditions. The 'C' option devices feature TTL input thresholds and an integrated noise filter to prevent transient pulses from affecting the output.

This digital isolator is suitable for applications requiring robust isolation between different voltage domains, such as in power supplies, motor control, and communication interfaces. Its quad-channel configuration provides flexibility in system design.
