Overview
The MC74HC4051ADWR2G is a single-channel analog multiplexer/demultiplexer manufactured by onsemi. It utilizes silicon-gate CMOS technology to achieve fast propagation delays, low ON resistances, and low OFF leakage currents. The device controls analog voltages varying across the complete power supply range from VCC to VEE. It features an Enable pin that turns off all switches when HIGH. The Channel-Select inputs determine which of the eight analog channels connects to the common output/input. The component operates with a digital supply voltage (VCC - GND) of 2.0 to 6.0 V and an analog supply range (VCC - VEE) of 2.0 to 12.0 V. It is housed in a 16-SOIC wide package.
Feature Summary
- Utilizes silicon-gate CMOS technology for improved linearity and lower ON resistance compared to metal-gate counterparts
- Provides diode protection on all inputs and outputs to guard against high static voltages
- Features low crosstalk between switches and low noise performance
- Compatible with standard CMOS outputs and LSTTL outputs using pullup resistors
Applications
- Analog signal routing in data acquisition systems
- Multiplexing multiple sensor inputs to a single ADC
- Audio signal switching applications
- Test and measurement equipment signal paths
Procurement Notes
Verify the specific ordering suffix 'DW' corresponds to the SOIC-16 Wide package (CASE 751G) as defined in the official datasheet. Confirm RoHS compliance status and check for any recent Product Change Notices regarding manufacturing site transfers or material declarations before finalizing procurement orders.
Selection Notes
Select this component when a single-pole eight-throw analog switch is required within a wide-voltage operational range. Ensure the application voltage does not exceed the maximum ratings of +7.0 V for VCC relative to GND and -7.0 V for VEE relative to GND. Consider external clipping diodes if voltage transients beyond the supply rails are anticipated on the analog channels.
Part Context
This part belongs to the MC74HC4051A family of high-performance silicon-gate CMOS analog multiplexers. It shares identical pinouts with the older metal-gate MC14051AB series but offers superior electrical characteristics including faster switching speeds and lower ON resistance. The device is designed to handle analog signals spanning the full power supply range.
Replacement Considerations
MC74HC4051ADWG is available in a rail package variant. NLV74HC4051ADR2G is an automotive qualified version with AEC-Q100 certification. Other manufacturers offer functionally similar parts such as the 74HC4051PW from Nexperia.
