The MAX4565/MAX4566/MAX4567 are low-voltage T-switches designed for switching RF and video signals from DC to 350MHz in 50Ω and 75Ω systems.
The MAX4565, MAX4566 and MAX4567 are low‑voltage, high‑frequency bidirectional RF/video switches designed for signal routing from DC to 350 MHz. They feature low power consumption, high off‑isolation and low crosstalk, and can operate with dual supplies (+2.7 V to +6 V) or a single +5 V supply.
The devices are offered in a variety of plastic and SOIC packages (e.g., 16‑pin DIP, 20‑pin Wide SO, QSOP) and are rated for temperatures from –40 °C to +85 °C. Detailed electrical characteristics, pin descriptions, and typical performance graphs are provided.
| Off‑Isolation (10 MHz) | -83 dB |
|---|---|
| Crosstalk (10 MHz) | -87 dB |
| Insertion Loss (100 MHz) | 2.5 dB |
| Supply Voltage Range (single +5 V) | +4.5 V to +5.5 V |
| Operating Temperature Range | -40 °C to +85 °C |
| Package Types | 16‑Pin DIP, 20‑Pin Wide SO, QSOP, etc. |
The devices provide an off‑isolation of –83 dB at 10 MHz.
Available packages include 16‑Pin Plastic DIP, 20‑Pin Wide SO, 20‑Pin SSOP, QSOP, and other surface‑mount variations.
The devices are rated from –40 °C to +85 °C.
