| DATASHEET 0.5 LOW VOLTAGE, SINGLE SPDT ANALOG SWITCH Description The IDTAS4624 low on-resistance (RON), low voltage, single-pole/double-throw (SPDT) analog switch operates from a single +1.8 V to +5.5 V supply. The IDTAS4624 features a 0.5 (max) RON for its NC switch and a 0.8 (max) RON for its NO switch at a +2.7 V supply. It also features break-before-make switching action (2 ns) with tON = 50 ns and tOFF = 40 ns at +3 V. The digital logic input is 1.8 V logic-compatible with a +2.7 V to +3.3 V supply.

These ratings, which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
