ESD protected logic level translators
for memory card apps
Intersil's new voltage logic level translators support
a data rate of 100 Megabit/second and offer high-ESD protection.
The new ISL3034E and ISL3035E are six-channel, auto-direction
sensing, bi-directional voltage level translators that ease
the interface between mixed supply voltage peripherals and
controllers.
The applications requiring this type of translators are
3.3V SD, mini SD, memory stick and multimedia card applications
that require I/O signal translation to the industry's latest
low-voltage system controllers.
The ISL3036E is the four-channel translator IC with same
specs.
The technical features include,
ESD rating of IEC61000-4-2 +/-15kV Air Gap, +/-9kV contact,
and +/-15kV HBM on all input, output and I/O lines.
The new voltage level translator (VLTs) operate with VCC
(SD card supply) voltages from +2.2V to +3.6V and VL voltages
from +1.35V to +3.2V.
Each I/O channel is pulled up to VCC or VL by an internal
30µA current source, allowing the VLTs to be driven
by either push-pull or open-drain drivers.
The ISL3034E and ISL3036E have enable (EN) input to place
the IC into a low-power shutdown mode when the input is
driven low.
All versions feature an automatic shutdown mode that places
the part in the same low power state when VCC is less than
VL.
The ISL3035E features a clock return output that returns
the same signal applied to the clock VL input, but with
a delay that better mimics the timing of data read back
from a memory card.
