SN74HC4851D

Overview

The SN74HC4851D is an eight-channel CMOS analog multiplexer/demultiplexer manufactured with silicon gate C2 MOS technology. 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 2V to 5.5V supply range and supports ambient temperatures from -40°C to 125°C. Key electrical parameters include a typical on-state resistance of 160Ω at 4.5V and a propagation delay of 8.6ns at 5V. Latch-up performance exceeds 100mA per JESD 78, Class II.

Feature Summary

Injection-current cross coupling less than 1mV/mA
Low crosstalk between switches
Terminal compatible with SN74HC4051, SN74LV4051A, and CD4051B devices

Applications

Analog and digital multiplexing and demultiplexing
Diagnostics and monitoring
Data center switch
Remote radio unit (RRU)
Rack server

Procurement Notes

Verify the specific package type and ordering suffix against the manufacturer's current documentation before procurement. Confirm that the selected variant meets the required thermal and environmental specifications for the intended application environment.

Selection Notes

Select this component when terminal compatibility with legacy '4051 series devices is required alongside injection-current protection. Ensure the operating voltage falls within the 2V to 5.5V range and verify that the 16-pin SOIC package dimensions fit the target PCB layout constraints.

Part Context

This device belongs to the Texas Instruments HC logic family, designed for high-speed CMOS applications. It serves as a direct pin-compatible replacement for older analog multiplexer technologies while offering improved signal integrity through internal injection-current suppression mechanisms.

Replacement Considerations

SN74HC4051, SN74LV4051A, CD4051B

FAQ

How does the injection-current effect control benefit automotive applications?

It allows signals at disabled input channels to exceed the normal supply voltage range without affecting the signal of the enabled analog channel, eliminating the need for external diode-resistor networks.
