DESCRIPTION
The ISO7220 and ISO7221 are dual-channel digital isolators. To facilitate PCB layout, the channels are oriented
in the same direction in the ISO7220 and in opposite directions in the ISO7221. These devices have a logic input
and output buffer separated by TI’s silicon-dioxide (SiO
4000 V. 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.
A binary input signal is conditioned, translated to a balanced signal, then differentiated by the capacitive isolation
barrier. 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 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 every 4 ms, the input is assumed to be
unpowered or not being actively driven, and the failsafe circuit drives the output to a logic high state.
The small capacitance and resulting time constant provide fast operation with signaling rates available from 0
Mbps (dc) to 150 Mbps.
(1)
The A-, B- 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 M-option devices have
CMOS V
/2 input thresholds and do not have the input noise-filter and the additional propagation delay.
CC
These devices require two supply voltages of 3.3 V, 5 V, or any combination. All inputs are 5-V tolerant when
supplied from a 3.3-V supply and all outputs are 4-mA CMOS.
These devices are characterized for operation over the ambient temperature range of –40°C to 125°C.
