These devices have two isolated channels. Each channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. Used in conjunction with isolated power supplies, these devices prevent noise currents on a data bus or other circuit from entering the local ground and interfering with or damaging sensitive circuitry. The suffix F indicates low-output option in fail-safe conditions (see Table 1). E-grade devices have no integrated noise filter and thus have fast propagation delays. CC-grade devices have integrated 10ns- filters for harsh environments where short noise pulses may be present at the device input pins. These devices have TTL input thresholds and operate from 3V to 5.5V supplies. All inputs are 5V tolerant when supplied from a 3.3V supply. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 DeviceNet is a trademark of Texas Instruments.
