DG428, DG429 Vishay Siliconix Single 8-Ch/Differential 4-Ch Latchable Analog Multiplexers FEATURES DESCRIPTION Halogen-free according to IEC 61249-2-21 The DG428, DG429 analog multiplexers have on-chip Definition address and control latches to simplify design in Low R : 55 DS(on) microprocessor based applications. Break-before-make Low Charge Injection: 1 pC switching action protects against momentary crosstalk of On-Board TTL Compatible Address Latches adjacent input signals. High Speed - t : 160 ns TRANS The DG428 selects one of eight single-ended inputs to a Break-Before-Make common output, while the DG429 selects one of four Low Power Consumption: 0.3 mW differential inputs to a common differential output. Compliant to RoHS Directive 2002/95/EC An on channel conducts current equally well in both directions. In the off state each channel blocks voltages up to BENEFITS the power supply rails. An enable (EN) function allows the Improved System Accuracy user to reset the multiplexer/demultiplexer to all switches off Microprocessor Bus Compatible for stacking several devices. All control inputs, address (A ) x Easily Interfaced and enable (EN) are TTL compatible over the full specified Reduced Crosstalk operating temperature range. High Throughput The silicon-gate CMOS process enables operation over a Improved Reliability wide range of supply voltages. The absolute maximum voltage rating is extended to 44 V. Additionally, single supply APPLICATIONS operation is also allowed and an epitaxial layer prevents Data Acquisition Systems latchup. Automatic Test Equipment On-board TTL-compatible address latches simplify the digital Avionics and Military Systems interface design and reduce board space in bus-controlled Communication Systems systems such as data acquisition systems, process controls, Microprocessor-Controlled Analog Systems avionics, and ATE.
