General Description
The MAX3000E/MAX3001E/MAX3002–MAX3012
8-channel level translators provide the level shifting necessary to allow data transfer in a multivoltage system.
Externally applied voltages, V
CC
and VL, set the logic levels on either side of the device. Logic signals present on
the V
L
side of the device appear as a higher voltage logic
signal on the V
CC
side of the device, and vice-versa.
The MAX3000E/MAX3001E/MAX3002/MAX3003 use an
architecture specifically designed to be bidirectional
without the use of a directional pin.
The MAX3000E/MAX3001E/MAX3002/MAX3004–MAX3012
feature an EN input that, when low, reduces the V
CC
and
VLsupply currents to < 2µA. The MAX3000E/MAX3001E
also have ±15kV ESD protection on the I/O V
CC
side for
greater protection in applications that route signals
externally. The MAX3000E operates at a guaranteed data
rate of 230kbps. The MAX3001E operates at a guaranteed
data rate of 4Mbps. The MAX3002–MAX3012 operate at a
guaranteed data rate of 20Mbps over the entire specified
operating voltage range.
The MAX3000E/MAX3001E/MAX3002–MAX3012 accept
VLvoltages from +1.2V to +5.5V and VCCvoltages from
+1.65V to +5.5V, making them ideal for data transfer
between low-voltage ASICs/PLDs and higher voltage
systems. The MAX3000E/MAX3001E/MAX3002–
MAX3012 are available in 20-bump UCSP™, 20-pin
TQFN (5mm x 5mm), and 20-pin TSSOP packages.
