CD74HCT4051ME4

Analog Switches, Multiplexers, Demultiplexers Overview

The CD74HCT4051ME4 is a high-speed CMOS logic analog multiplexer switch manufactured by Texas Instruments. It features an 8:1 configuration within a single circuit, housed in a 16-SOIC surface-mount package. The device operates on a single supply voltage ranging from 4.5 V to 5.5 V, or dual supplies between ±1 V and ±5 V. Key electrical parameters include a maximum on-resistance of 130 Ohms, a -3 dB bandwidth of 180 MHz, and a propagation delay of 4 ns. It supports an operating temperature range from -55°C to +125°C and complies with RoHS3 standards.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official datasheet specifications. Confirm the presence of the 'E4' suffix which indicates lead-free composition and compliance with current environmental regulations. Ensure the SOIC-16 package dimensions match the target PCB footprint requirements before integration into production assemblies.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single 8-to-1 analog switch is required within a high-speed digital environment. The HCT logic interface ensures compatibility with standard TTL-level control signals. Consider the 130 Ohm on-resistance limit for signal integrity constraints and verify that the 180 MHz bandwidth meets the frequency requirements of the intended application signals.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the CD74HCT4051 family of analog multiplexers produced by Texas Instruments. It is functionally compatible with other industry-standard 74HCT4051 devices but offers specific manufacturing attributes defined by the TI product line. The ME4 designation identifies the specific tape-and-reel packaging variant of the SOIC-16 package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include the CD74HCT4051M and CD74HCT4051M96 from Texas Instruments. Other manufacturers such as Nexperia offer equivalent parts like the 74HCT4051D series, though parameter verification is necessary.
