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 VCC and VL supply
voltages set the logic levels on either side of the device.
Logic signals present on the IC’s VL side appear as higher
voltage logic signals on the IC’s VCC side and vice versa.
The ISL3035E features a CLK_RET output that returns the
same clock signal applied to the CLK_VL input, but with
timing that mimics the data returning from the I/OVCC 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 VCC or VL 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 VCC is less than VL. The
states of I/OVCC and I/OVL during shutdown are chosen by
selecting the appropriate product (see Table 1).
The ISL3034E, ISL3035E, ISL3036E operate with VCC
voltages from +2.2V to +3.6V and VL voltages from +1.35V
to +3.2V, making them ideal for data transfer between
low-voltage microcontrollers or ASICs and higher voltage
components.
