MX856 and MX857 (Data Sheet) 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, amplify them to the VCC and GND supply rails, and generate 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.
