The IL715, IL716 and IL717 series of 4channel digital isolators provide the designer with the most compact isolated 5V logic devices yet available. These isolators are packaged in three options: IL715 with four unidirectional channels, IL716 with two channels in one direction and two channels in the opposite direction, and the IL717 with three channels in one direction and one channel in the other direction. All these devices are fabricated with patented* IsoLoop® technology giving them excellent transient immunity specifications. The symmetric magnetic coupling barrier gives these isolators a propagation delay of only 10 ns and a pulse width distortion of 2 ns. Devices are 100% high voltage tested to guarantee barrier integrity.
The IL715, IL716 and IL717 have a 100 MBaud data rate which is independent of direction. They are available in 16pin SOIC packages and are specified over the temperature range 40ºC to +100ºC.
The IL74 is an optically coupled pair with a Gallium Arsenide infrared LED and a silicon NPN phototransistor. Signal information, including a DC level, can be transmitted by the device while maintaining a high degree of electrical isolation between input and output. The IL74 is especially designed for driving medium-speed logic, where it may be used to eliminate troublesome gound loop and noise problems. Also it can be used to replace relays and transformers in many digital interface applications, as well as analog applications such as CRT modulation.
The ILD74 has two isolated channels in a single DIP package; the ILQ74 has four isolated channels per package.
