The MX856 and MX857 are high speed,
single-channel level shifters with complementary
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
complementary 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 in an 8-lead SOIC package.

1.7 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.
