Low On-Resistance: 2 TTL and CMOS Logic Compatible Low Power: 3 mw Break-Before-Make Switching -V Power Supply Rating Transition Time: ns Easily Interfaced Low Power Consumption Low System Crosstalk Wide Analog Signal Range Communication Systems ATE ata Acquisition Systems Audio Signal Routing and Multiplexing Medical Instrumentation The G58A_MIL, an 8-channel single-ended analog multiplexer, is designed to connect one of eight inputs to a common output as determined by a 3-bit binary address (A,, ). The G59A_MIL, a dual -channel analog multiplexer, is designed to connect one of four differential inputs to a common output as determined by its 2-bit binary address (A, ) logic. Break-before-make switching action protects against momentary shorting of the input signals. enable () are TTL or CMOS compatible over the full specified operating temperature range. Fabricated in the Plus- process, the absolute maximum voltage rating is extended to V, allowing increased operating headroom for standard 15-V signal swings and operation with 2-V supplies. An epitaxial layer prevents latch up. The G58A_MIL/59A_MIL are available in hermetic packages. For plastic packages, use the G8/9 as pin-for-pin replacements. 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 3 V peak-to-peak. An enable () function allows for device selection when several multiplexers are used All control inputs, address (A X ) and For applications requiring address data latching, the G528/529 is recommended. G8/9 is recommended for higher precision applications. For wideband/video routing and multiplexing, the G538A is recommended.

Operation below 8 V is not recommended. Overvoltage Protection v V g v 1N18 A very convenient form of overvoltage protection consists of adding two small signal diodes (1N18, 1N91 type) in series with the supply pins (see Figure 11). This arrangement effectively blocks the flow of reverse currents. It also floats the supply pin above or below the normal or 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 V S and the rail doesn t exceed + V. The addition of these diodes will reduce the analog signal range to 1 V below and 1 V above, but it preserves the low channel resistance and low leakage characteristics.
