74VHC4052AFT

Analog Switches, Multiplexers, Demultiplexers Overview

The Toshiba 74VHC4052AFT is a dual 4-channel analog multiplexer/demultiplexer IC manufactured in the 74VHC logic series. It operates on a single supply voltage ranging from 2 V to 5.5 V and features four independent SP4T switch circuits within two channels. The device utilizes TSSOP-16 surface-mount packaging with dimensions of 5.00 x 4.40 mm and a height of 1.20 mm. Key electrical specifications include a maximum on-resistance of 37 Ohms, a bandwidth of 230 MHz, and low leakage current of 100 nA. Switching times are specified at a maximum of 12 ns for both turn-on and turn-off periods. The component supports an operating temperature range of -40°C to +85°C and holds AEC-Q100 qualification.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm package type and reel specifications. Ensure the procurement source provides valid RoHS compliance documentation. Confirm that the delivered units match the active part status and AEC-Q100 automotive qualification requirements. Check for moisture sensitivity level 1 handling instructions during storage and assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 4:1 analog switching is required within a compact TSSOP-16 footprint. The 74VHC series offers faster switching speeds compared to standard HC logic while maintaining compatibility with 5 V and lower voltage systems. Consider the 37 Ohm on-resistance limit for signal integrity requirements in high-frequency applications up to 230 MHz.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the Toshiba 74VHC4052 family of CMOS analog switches. It serves as a functional equivalent to industry-standard 74VHC4052 parts but is specifically manufactured by Toshiba Semiconductor and Storage. The 'AFT' suffix denotes the specific TSSOP-16 surface mount package variant available in tape and reel formats for automated assembly.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The 74VHC4052D is a documented alternative from the same manufacturer offering similar functionality in an SOIC-16 package. Verify pinout compatibility and package dimensions before substituting the D variant for the FT variant in existing designs.
