高电压闩锁防 High Voltage Latch-Up Proof
Product Details
The ADG5236 is a monolithic CMOS device containing two independently selectable single-pole/double throw SPDT switches. An EN input on the LFCSP package enables or disables the device. When disabled, all channels switch off. Each switch conducts equally well in both directions when on and has an input signal range that extends to the supplies. In the off condition, signal levels up to the supplies are blocked. Both switches exhibit break-before-make switching action for use in multiplexer applications.
The ultralow capacitance and charge injection of these switches make them ideal solutions for data acquisition and sample-and-hold applications, where low glitch and fast settling are required. Fast switching speed together with high signal bandwidth make the device suitable for video signal switching.

**PRODUCT HIGHLIGHTS**
1. Trench Isolation Guards Against Latch-Up.
A dielectric trench separates the P and N channel transistors thereby preventing latch-up even under severe overvoltage conditions.
2. Ultralow capacitance and < 1 pC charge injection.
3. Dual-Supply Operation.
For applications where the analog signal is bipolar, the ADG5236 can be operated from dual supplies up to ±22 V.
4. Single-Supply Operation.
For applications where the analog signal is unipolar, the ADG5236 can be operated from a single rail power supply up to 40 V.
5. 3 V Logic Compatible Digital Inputs.
VINH = 2.0 V, VINL = 0.8 V.
6. No VL Logic Power Supply Required.
