IDTAS4624 is a low voltage single-pole/double-throw analog switch from IDT, with a working voltage range of 1.8V to 5.5V and a switch resistance of 0.5 ohms (maximum).
The IDTAS4624 analog switch offers low on‑resistance (0.5 Q for NC, 0.8 Q for NO) and rail‑to‑rail signal handling across a single‑supply range of 1.8 V to 5.5 V. It features break‑before‑make switching (2 ns) with turn‑on/off times around 30‑50 ns, high off‑isolation (‑64 dB at 100 kHz), and low leakage currents (1 nA typical).
The device is supplied in a 6‑pin SOT‑23 package and includes pin assignments, truth tables, absolute maximum ratings, and detailed electrical characteristics for both +3 V and +5 V supply conditions. Revision history and contact information are provided at the end of the document.
| Supply voltage range | 1.8 V to 5.5 V |
|---|---|
| Off‑isolation (100 kHz) | -64 dB |
| Crosstalk (100 kHz) | -68 dB |
| Total Harmonic Distortion (THD) | 0.03 % |
It operates from a single 1.8 V to 5.5 V supply.
The off‑isolation is approximately –64 dB at 100 kHz.
