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
