Description
The MX856 and MX857 are high speed,
single-channel level shifters with complementary
output drivers. The MX856 features a 5.0V VCC
positive supply, and the MX857 features a 3.3V VCC
positive supply.
The input buffers accept digital TTL or CMOS level
signals, amplifies them to the VCC and GND supply
rails, and generates complementary outputs. The
translator level shifts these output signals by
amplifying them to the VCC and VEE supply rails.
The output drivers then buffer the signals to VOPT and
VEE. VOPT may be set within the range of VCC 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.
