The DG411F/DG412F/DG413F are quad, single-pole/sin- gle-throw (SPST), fault-protected analog switches. They are pin compatible with the industry-standard nonpro- tected DG411/DG412/DG413. These new switches fea- ture fault-protected inputs and Rail-to-Rail signal- handling capability. All terminals are protected from overvoltage faults up to ±36V with power on and up to ±40V with power off. During a fault condition, the COM, NO, or NC terminal becomes an open circuit and only microamperes of leakage current flow from the source. On-resistance is 35Ω (max) and is matched between switches to 1.5Ω (max) at +25°C. The DG411F has four normally closed (NC) switches. The DG412F has four normally open (NO) switches. The DG413F has two NC and two NO switches. These CMOS switches operate with dual power supplies rang- ing from ±4.5V to ±20V or a single supply between +9V and +36V. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring both TTL and CMOS logic com- patibility when using ±15V or a single +12V supply. For supply voltages of ±5V, +5V, and +3V, refer to the MAX4711/MAX4712/MAX4713 data sheet.

The MAX4708/MAX4709 are 8-to-1 and dual 4-to-1 fault-protected multiplexers that are pin compatible with the industry-standard DG508/DG509. The MAX4708/MAX4709 are similar to the MAX4508/MAX4509, but these devices do not have clamp diodes to the supply rails on the switch outputs. These multiplexers feature fault-protected inputs, rail-to-rail signal-handling capability, and do not require power-supply sequencing. Both devices offer ±40V overvoltage protection with the supplies off, ±36V protection with the supplies on, and feature 400Ω (max) on-resistance with 15Ω (max) matching between channels. The MAX4708/MAX4709 operate with dual supplies of ±4.5V to ±20V or a single supply of +9V to +36V. All digital inputs have TTL logic-compatible thresholds, ensuring both TTL and CMOS logic compatibility when using a single +12V supply or dual ±15V supplies. For low-voltage applications requiring fault protection, refer to the MAX4711/MAX4712/MAX4713 data sheet. Applications include data-acquisition systems, industrial and process control, avionics, signal routing, redundancy/backup systems, ATE systems, and hot swap systems.

The MAX4937/MAX4939 include just the T/R switch and perform the receive operation only. The MAX4936/MAX4938 transmit path is low impedance during high-voltage transmit and high impedance during low-voltage receive, providing isolation between transmit and receive circuitry. The high-voltage transmit path is high bandwidth, low distortion, and low jitter. The receive path for all devices is low impedance during low-voltage receive and high impedance during high-voltage transmit, providing protection to the receive circuitry. The low-voltage receive path is high bandwidth, low noise, low distortion, and low jitter.
