Single-supply dual DPDT analog switch
26 September 2001
Power Electronics / Power Management
ON Semiconductor's NLAS44599/NLAST44599 devices are advanced CMOS double pole, double throw analog switches. CMOS and TTL compatible input versions are available. These devices can control analog and digital voltages from Vcc to GND. They can be used as a quad 2-to-1 multiplexer-demultiplexer analog switch.
Key features are:
* Overvoltage tolerant inputs up to +5,5 V (allows interfacing to multiple voltage systems).
* Improved linearity and lower on-resistance over input voltage (reduced signal distortion).
* Low power dissipation: ICC=2 µA (max) at TA = 25°C (reduces total system power).
* High speed: tPD = 1 ns (typ) at VCC = 5 V (minimises system delay).
* Diode protection provided on channel select input (prevents device destruction from 0 to 5,5 V).
