MC74HC4851A, MC74HC4852A Analog Multiplexers/ Demultiplexers with Injection Current Effect www.onsemi.com Control Automotive Customized These devices are pin compatible to standard HC405x and MC1405xB analog mux/demux devices, but feature injection current SOIC16 SOIC16 WIDE D SUFFIX DW SUFFIX effect control. This makes them especially suited for usage in CASE 751B CASE 751G automotive applications where voltages in excess of normal logic voltage are common. The injection current effect control allows signals at disabled analog 1 input channels to exceed the supply voltage range without affecting TSSOP16 QFN16 the signal of the enabled analog channel. This eliminates the need for DT SUFFIX MN SUFFIX external diode/resistor networks typically used to keep the analog CASE 485AW CASE 948F channel signals within the supply voltage range. The devices utilize low power silicon gate CMOS technology. MARKING DIAGRAMS The Channel Select and Enable inputs are compatible with standard CMOS outputs. 16 16 HC4851A Features HC485xAG AWLYWWG AWLYWW Injection Current CrossCoupling Less than 1 mV/mA (See 1 Figure 10) 1 SOIC16 Pin Compatible to HC405X and MC1405XB Devices SOIC16 WIDE Power Supply Range (V GND) = 2.0 to 6.0 V 16 CC In Compliance With the Requirements of JEDEC Standard No. 7 A HC48 5xA 4851 Chip Complexity: 154 FETs or 36 Equivalent Gates ALYW ALYW NLV Prefix for Automotive and Other Applications Requiring 1 Unique Site and Control Change Requirements AECQ100 TSSOP16 QFN16* Qualified and PPAP Capable *V4851 marking used for These Devices are PbFree, Halogen Free and are RoHS Compliant NLV74HC4851AMN1TWG x = 1 or 2 A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week G or = PbFree Package (Note: Microdot may be in either location) ORDERING INFORMATION See detailed ordering and shipping information in the package dimensions section on page 12 of this data sheet.
