Description
PI5A4594A/PI5A4596A are single-pole/single-throw (SPST) ana-
log switches that operate from a single +2.0V to +5.5V supply. The
PI5A4594A/PI5A4596A switches are normally open (NO), and the
PI5A4595A/PI5A4597A are normally closed (NC). The PI5A4596A/
PI5A4597A pinouts are optimized for the highest SC70 package
off-isolation available.
These switches have 10-ohm max On-Resistance (R_ON), with 1.5-
ohms max R_ON flatness over the analog signal range when powered
from a +5V supply. Leakage currents are 0.5nA and fast switching
times are less than 40ns. They are packaged in a compact 5-pin
SC70 package.
Applications
• Cellular Phones • Communications Circuits
• Battery-Operated Equipment • DSL Modems
• Audio and Video Signal Routing • PCMCIA Cards
