MX857B

MX856/MX857 Single Driver for Attenuators and GaAs FET Switches Characteristics Description Parameter Rating Units Output Voltage 20 V Output Rise Time 5 ns Output Fall Time 5 ns 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. Features • • • • • • • • CMOS Technology TTL/CMOS Compatible Inputs Low Switching Noise 5nS Typical True / Complement Output Skew 5nS Typical Output Rise and Fall Times Up to 20V Output Voltage Output High Voltage Programmable Via VOPT Output Low Voltage Programmable Via VEE 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. 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 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.
