The ISO7240A, ISO7241A and ISO7242A are quad-channel digital isolators with multiple channel configurations and output enable functions. These devices have logic input and output buffers separated by TI’s silicon dioxide (SiO2) isolation barrier. Used in conjunction with isolated power supplies, these devices block high voltage, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry. The ISO7240A has all four channels in the same direction while the ISO7241A has three channels the same direction and one channel in opposition. The ISO7242A has two channels in each direction. The devices have TTL input thresholds and a noise-filter at the input that prevents transient pulses from being passed to the output of the device. A periodic update pulse is sent across the barrier to ensure the proper dc level of the output. If this dc-refresh pulse is not received, the input is assumed to be unpowered or not being actively driven, and the failsafe circuit drives the output to a logic high state. (See ISO7240CF (SLLS869) or contact TI for a logic low failsafe option). These devices may be powered from either 3.3-V or 5-V supplies on either side in any 3.3-V / 3.3-V, 5-V / 5-V, 5-V / 3.3-V, or 3.3-V / 5-V combination. Note that the signal input pins are 5-V tolerant regardless of the voltage supply level being used. These devices are characterized for operation over the ambient temperature range of –40°C to 125°C.

The output locks in a logic-low condition until the next rising edge occurs after a 1 ms period. Positive noise edges in pulses of less than the minimum specified 1 ms have no effect on the device, and are properly filtered. To prevent noise from interfering with ISO724xA performance, it is recommended that an appropriately sized capacitor be placed on each input of the device Figure 11.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
