The AD8186/AD8187 are 480MHz single-supply (5V) triple 2:1 multiplexers from Analog Devices.
The AD8186 (gain = +1) and AD8187 (gain = +2) are 480 MHz single‑supply, triple 2‑to‑1 video multiplexers offered in a 24‑lead TSSOP package. They provide fast 4 ns channel‑to‑channel switching, low crosstalk, and a high‑impedance disable feature for building larger input arrays.
Key specifications include a small‑signal bandwidth of up to 1000 MHz, low quiescent current (<20 mA at 5 V), and robust ESD protection. The devices are suited for RGB switching in LCD/plasma displays, video routers, and other high‑speed video applications.
| Small‑Signal Bandwidth (‑3 dB) | 1000 MHz |
|---|---|
| Large‑Signal Bandwidth (‑3 dB) | 480 MHz (AD8187) / 450 MHz (AD8186) |
| Power Supply Operating Range | 3.5 V – 5.5 V |
| Quiescent Current (All Channels ON) | 18.5 mA (AD8186) / 19.5 mA (AD8187) |
| OFF Isolation (5 MHz) | -84 dB (AD8186) / -95 dB (AD8187) |
| Input Resistance @100 kHz | 1.8 MΩ (AD8186) / 1.3 MΩ (AD8187) |
The AD8186 switches in 3.6 ns and the AD8187 in 4 ns (50 % logic to 50 % output settling).
Both devices are supplied in a 24‑lead Thin Shrink Small Outline Package (TSSOP, RU‑24).
The quiescent current is 18.5 mA for the AD8186 and 19.5 mA for the AD8187.
