DG458, DG459 Vishay Siliconix Fault-Protected Single 8-Ch/Differential 4-Ch Analog Multiplexers DESCRIPTION FEATURES The DG458 and DG459 are 8-channel single-ended and • • • • • • • • 4-channel differential analog multiplexers, respectively, incorporating fault protection. A series n-p-n MOSFET structure provides device and signal-source protection in the event of power loss or overvoltages. Under fault conditions the multiplexer input (or output) appears as an open circuit and only a few nanoamperes of leakage current will flow. Fault and Overvoltage Protection All Channels Off When Power Off Latchup-Proof Fast Switching - tA: 200 ns Break-Before-Make Switching Low On-Resistance: 180 W Low Power Consumption: 3 mW TTL and CMOS Compatible Inputs This protects not only the multiplexer and the circuitry following it, but also protects the sensors or signal sources BENEFITS which drive the multiplexer. • • • • • • The DG458 and DG459 can withstand continuous overvoltage inputs up to ± 35 V. All digital inputs have TTL compatible logic thresholds. Break-before-make operation prevents channel-to-channel interference. The DG458 and DG459 are improved pin-compatible replacements for HI-508A/509A and MAX358/359 multiplexers. Improved Ruggedness Power Loss Protection Prevents Adjacent Channel Crosstalk Standard Logic Interface Superior Accuracy Fast Settling Time APPLICATIONS • • • • • Data Acquisition Systems Industrial Process Control Systems Avionics Test Equipment High-Rel Control Systems Telemetry FUNCTIONAL BLOCK DIAGRAM AND PIN CONFIGURATION DG459 DG458 Dual-In-Line Dual-In-Line A0 EN VS1 S2 S3 S4 D 16 1 2 Decoders/Drivers 15 3 14 4 13 5 12 6 11 7 10 8 9 A1 A0 A2 EN GND V- V+ S1a S5 S2a S6 S3a S7 S4a S8 Da Top View 16 1 2 Decoders/Drivers 15 3 14 4 13 5 12 6 11 7 10 8 9 A1 GND V+ S1b S2b S3b S4b Db Top View * Pb containing terminations are not RoHS compliant, exemptions may apply Document Number: 70064 S11-1029–Rev.

These multiplexers are built on a high-voltage junction-isolated silicon-gate CMOS process. Two n-channel and one p-channel MOSFETs are connected in series to form each channel (Figure 1). Within the normal analog signal range (± 10 V), the RDS(on) variation as a function of analog signal voltage is comparable to that of the classic parallel N-MOS and P-MOS switches. - 35 V Overvoltage n-Channel MOSFET is On Q1 - 35 V S D G Q2 S D G Q3 S + 35 V Overvoltage D n-Channel MOSFET is Off G p-Channel MOSFET is Off (a) Overvoltage with Multiplexer Power Off When the analog signal approaches or exceeds either supply rail, even for an on-channel, one of the three series MOSFETs gets cut-off, providing inherent protection against overvoltages even if the multiplexer power supply voltages are lost. This protection is good up to the breakdown voltage of the respective series MOSFETs. Under fault conditions only sub microamp leakage currents can flow in or out of the multiplexer. This not only provides protection for the multiplexer and succeeding circuitry, but it allows normal, undisturbed operation of all other channels. Additionally, in case of power loss to the multiplexer, the loading caused on the transducers and signal sources is insignificant, therefore redundant multiplexers can be used on critical applications such as telemetry and avionics. - 15 V Q1 - 35 V Overvoltage n-Channel MOSFET is On + 15 V - 15 V Q2 + 15 V - 15 V Q3 + 35 V Overvoltage n-Channel MOSFET is Off p-Channel MOSFET is Off (b) Overvoltage with Multiplexer Power On Figure 5.
