    44 V Supply Maximum Ratings VSS to VDD Analog Signal Range Low On Resistance (60 u2340 typ) Low Power Consumption (1.6 mW max) Low Charge Injection (<4 pC typ) Fast Switching Break-Before-Make Switching Action Plug-In Replacement for DG428/DG429



The ADG428 and ADG429 are monolithic CMOS analog multiplexers comprising eight single channels and four differen- tial channels respectively. On-chip address and control latches facilitate microprocessor interfacing. The ADG428 switches one of eight inputs to a common output as determined by the 3-bit binary address lines A0, A1 and A2. The ADG429 switches one of four differential inputs to a common differential output as determined by the 2-bit binary address lines A0 and A1. An EN input on both devices is used to enable or disable the device. When disabled, all channels are switched OFF. All the control inputs, address and enable inputs are TTL compatible over the full specified operating temperature range. This makes the part suitable for bus-controlled systems such as data acquisition sys- tems, process controls, avionics and ATEs because the TTL- compatible address latches simplify the digital interface design and reduce the board space required. The ADG428/ADG429 are designed on an enhanced LC2 MOS process that provides low power dissipation yet gives high switching speed and low on resistance. Each channel conducts equally well in both directions when ON and has an input signal range that extends to the supplies. In the OFF condition, signal levels up to the supplies are blocked. All channels exhibit break-before-make switching action, preventing momentary shorting when switching channels. Inherent in the design is low charge injection for mini- mum transients when switching the digital inputs. The ADG428/ADG429 are improved replacements for the DG428/DG429 Analog Multiplexers.
