ISL3034E, ISL3035E,
4-Channel And 6-Channel High Speed, Auto-direction Sensing Logic Level
Translators
The ISL3034E, ISL3035E, ISL3036E 4- and 6-channel
bi-directional, auto-direction sensing, level translators
provide the required level shifting in multi-voltage systems at
data transfer rates up to 100Mbps. The auto-direction
sensing feature makes the ISL3034E, ISL3035E, ISL3036E
ideally suited for memory-card level translation (or for
generic four to six channel level translation) especially if
bit-by-bit direction control is desired. The V
CC
and V
L
supply
voltages set the logic levels on either side of the device.
Logic signals present on the IC’s V
L
side appear as higher
voltage logic signals on the IC’s V
CC
side and vice versa.
The ISL3035E features a CLK_RET output that returns the
same clock signal applied to the CLK_V
L
input, but with
timing that mimics the data returning from the I/OV
CC
inputs.
The ISL3034E, ISL3035E, ISL3036E operate at full speed
with external input drivers that source as little as 4mA output
current. Each I/O channel is pulled up to V
CC
or V
L
by an
internal 30µA current source, allowing the ISL3034E,
ISL3035E, ISL3036E to be driven by either push-pull or
open-drain drivers.
The ISL3034E and ISL3036E include an enable (EN) input
that when driven low places the IC into a low-power
shutdown mode, with all I/O lines tri-stated. All versions
feature an automatic shutdown mode, that places the part in
the same shutdown state when V
CC
is less than V
L
. The
states of I/OV
CC
and I/OV
L
during shutdown are chosen by
selecting the appropriate product (see Table 1).
The ISL3034E, ISL3035E, ISL3036E operate with V
CC
voltages from +2.2V to +3.6V and V
L
voltages from +1.35V
to +3.2V, making them ideal for data transfer between
low-voltage microcontrollers or ASICs and higher voltage
components.
