DESCRIPTION
A channel in the on state conducts current equally well in both directions. In the off state each channel blocks voltages up to the power supply rails, normally 30 V peak-to-peak. An enable (EN) function allows for device selection when several multiplexers are used. All control inputs, address (AX) and enable (EN) are TTL or CMOS compatible over the full specified operating temperature range. ESD protection for ruggedness. An epitaxial layer prevents latch up.
The DG506A_MIL/507A_MIL are available in hermetic packages. For plastic packages, use the DG406/407 as pin-for-pin replacements. For wideband/video recommended. multiplexing, the DG536 is
The DG506A_MIL/507A_MIL are fabricated in the Vishay Siliconix PLUS-40 process, which includes improved

Notes: a. Application Hints are for DESIGN AID ONLY, not guaranteed and not subject to production testing. b. Electrical Parameter Chart based on V+ = 15 V, V- = -15 V. c. Operation below "8 V is not recommended due to shift in VINL(MAX).
Overvoltage Protection A very convenient form of overvoltage protection consists of adding two small signal diodes (1N4148, 1N914 type) in series with the supply pins (see Figure 5). This arrangement effectively blocks the flow of reverse currents. It also floats the supply pin above or below the normal V+ or V- value. In this case the overvoltage signal actually becomes the power supply of the IC. From the point of view of the chip, nothing has changed, as long as the difference between VS and the V- rail doesn't exceed +44 V. The addition of these diodes will reduce the analog signal range to 1 V below V+ and 1 V above V-, but it preserves the low channel resistance and low leakage characteristics.
