LTC1390CS#PBF

LTC1390 is a high performance CMOS 8-to-1 analogue multiplexer. It features a 3-wire digital interface with a bidirectional data retransmission feature, allowing it to be wired in series with a serial A/D converter while using only one serial port. The interface also allows several device's to be wired in series or parallel, increasing the number of MUX channels available using only a single digital port. All the above features are also valid when device operates as a demultiplexer such as with a D/A converter. It features a typical RON of 45 ohm, typical switch leakage of 50pA, and guaranteed break-before-make operation. Charge injection is ±10pC maximum. All digital inputs are TTL and CMOS compatible when operated from single or dual supplies. The inputs can withstand 100mA fault currents. It is used in application such as data acquisition systems, communication systems, signal multiplexing/demultiplexing etc.

• Single supply operation is 3V to ±5V
• Analog inputs may extend to supply rails

• Clock frequency is 5MHz max at (V+ = 5V, V– = –5V, GND = 0V)
• Off isolation is 70dB typical at (VS = 2VP-P, RL = 1K, f = 100KHz)
• Operating temperature is 0°C to 70°C
• Package style is 16-lead plastic SOIC
