Overview
The Nexperia 74HC4051DB,112 is an 8-channel analog multiplexer/demultiplexer housed in a 16-lead SO plastic small outline package (SOT109-1). It operates as a single-pole octal-throw switch with three digital select inputs and one active-low enable input. The device supports a wide analog input voltage range from -5 V to +5 V and complies with JEDEC standards JESD8C (2.7 V to 3.6 V) and JESD7A (2.0 V to 6.0 V). Typical ON resistance values are 80 Ω at VCC - VEE = 4.5 V, 70 Ω at 6.0 V, and 60 Ω at 9.0 V. It features built-in ESD protection exceeding 2000 V (HBM) and 1000 V (CDM), with latch-up performance exceeding 100 mA per JESD 78 Class II Level B.
Feature Summary
- Provides low ON resistance for efficient signal transmission across varying supply differentials.
- Includes clamp diodes on inputs to allow interfacing with voltages exceeding VCC using current limiting resistors.
- Offers typical 'break before make' switching action to prevent signal shorting during channel transitions.
Applications
- Analog multiplexing and demultiplexing
- Digital multiplexing and demultiplexing
- Signal gating
Procurement Notes
Verify the ordering suffix matches the specific package variant required for your design constraints. Confirm that the temperature range specification aligns with your operational environment requirements. Ensure compatibility with the intended logic family levels before finalizing procurement decisions.
Selection Notes
Select this component when an 8:1 analog routing solution is needed within standard CMOS logic families. Consider the SO16 package dimensions against available PCB space. Evaluate the ON resistance characteristics relative to your signal amplitude and frequency requirements to ensure minimal signal degradation.
Part Context
This part belongs to the 74HC/HCT4051 series of 8-channel analog switches manufactured by Nexperia. It shares functional pinouts with industry-standard equivalents but offers specific electrical characteristics defined by Nexperia's manufacturing processes. The DB suffix indicates the SO16 package configuration.
Replacement Considerations
Direct replacements include other 74HC4051 variants from different manufacturers that adhere to the same pinout and electrical specifications. Verify package compatibility and thermal dissipation limits when substituting.
