MC74HC4851ADR2G-Q

Overview

The MC74HC4851ADR2G-Q is an automotive-grade analog multiplexer/demultiplexer manufactured by onsemi. It features injection current effect control, allowing signals at disabled channels to exceed the supply voltage without affecting the enabled channel. The device operates within a DC supply voltage range of 2.0 V to 6.0 V and supports an operating temperature range from -55°C to +125°C. It utilizes low power silicon gate CMOS technology and is housed in a 16-SOIC surface-mount package.

Feature Summary

Injection current cross-coupling less than 1 mV/mA
Pin compatible with HC405X and MC1405XB devices
Compliant with AEC-Q100 qualification standards
PPAP capable for automotive applications

Applications

Automotive sensor signal routing
Microcontroller analog input scanning
Data acquisition systems requiring high-voltage tolerance

Procurement Notes

Verify the specific ordering suffix matches the required package type and tape & reel specifications. Confirm that the component meets the unique site and control change requirements mandated by the -Q suffix for automotive production parts. Ensure compliance with RoHS and REACH directives as stated in the datasheet.

Selection Notes

Select this component when standard analog muxes fail due to injection current effects from out-of-range signals. The device eliminates the need for external diode/resistor networks typically used to clamp signals. Verify that the logic family (HC vs HCT) matches the system voltage levels, as this part is specified for the HC series.

Part Context

This device belongs to the MC74HC4851A family of analog multiplexers. It shares pin compatibility with legacy 405x series devices but offers superior performance in environments with voltage spikes. The -Q suffix indicates it is qualified for automotive use with specific manufacturing controls.
