General Description
The MX856 and MX857 are high speed single
channel level shifters with complimentary output
drivers. The MX856 features a 5.0V V
CC
positive
supply, and the MX857 features a 3.3V V
CC
positive supply.
The input buffers accept digital TTL or CMOS level
signals, amplifies them to the V
CC
and GND supply
rails, and generates complementary outputs. The
translator level shifts these output signals by
amplifying them to the V
CC
and V
EE
supply rails.
The output drivers then buffer the signals to V
OPT
and V
EE
. V
OPT
may be set within the range of V
CC
and GND. The output drivers also adjust the
complimentary signals for minimized skew error.
The MX856 and MX857 are designed to operate
over a temperature range of -40°C to +85°C, and
are available as die in wafer form, die in waffle
pack, 8 lead SOIC package, and SOIC on Tape
and Reel.
Applications
•
Digital control of analog circuits
•
Level shifting and amplification
•
Circuit applications requiring complementary
signal generation with low skew
•
Bias control for PIN diode drivers in a
microwave switch

Absolute Maximum Ratings are stress ratings. Stresses in excess of these ratings can cause
permanent damage to the device. Functional operation of the device at these or any other conditions
beyond those indicated in the operational sections of this data sheet is not implied. Exposure of the
device to the absolute maximum ratings for an extended period may degrade the device and affect
its reliability.

ESD Warning
ESD (electrostatic discharge) sensitive device. Electrostatic charges can readily accumulate on test equipment and the human body
in excess of 4000 Volts. This energy can discharge without detection. Although the MX856 / MX857 feature proprietary ESD
protection circuitry, permanent damage may be sustained if subjected to high energy electrostatic discharges. Proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
