![]() Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. ![]() Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device.

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. The signaling rate of a line is the number of voltage transitions that are made per second expressed in the units bps (bits per second). These devices are characterized for operation over the ambient temperature range to 125☌. All inputs are 5-V tolerant when supplied from a 3.3-V supply and all outputs are 4-mA CMOS. These devices require two supply voltages V, or any combination. The M-option devices have CMOS Vcc/2 input thresholds and do not have the input noise-filter and the additional propagation delay. (1)The A- and C-option 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. The small capacitance and resulting time constant provide very fast operation with signaling rates available from 0 Mbps (DC) to 150 Mbps. If this dc-refresh pulse is not received every 4 s, the input is assumed to be unpowered or not being actively driven, and the failsafe circuit drives the output to a logic high state. A periodic update pulse is sent across the barrier to ensure the proper dc level of the output. Across the isolation barrier, a differential comparator receives the logic transition information, then sets or resets a flip-flop and the output circuit accordingly. A binary input signal is conditioned, translated to a balanced signal, then differentiated by the capacitive isolation barrier. Used in conjunction with isolated power supplies, these devices block high voltage, isolate grounds, and prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. These devices have a logic input and output buffer separated by TI's silicon-dioxide (SiO2) isolation barrier, providing galvanic isolation 4000 V. To facilitate PCB layout, the channels are oriented in the same direction in the ISO7220 and in opposite directions in the ISO7221. The ISO7220 and ISO7221 are dual-channel digital isolators.
