Overview

The Nexperia HEF4066BT,653 is a quad bilateral analog switch designed for high-impedance signal routing and multiplexing applications. Its primary function is to provide low-distortion signal path switching across a wide voltage range, with a key operational characteristic being its relatively low on-resistance (155Ω max). A critical design consideration for engineers is managing the trade-off between this on-resistance and the device’s bandwidth (90MHz), as higher on-resistance inherently limits the usable frequency range for accurate signal transfer, especially in sensitive analog circuits.

Key Features

On-State Resistance (Max): 155Ω
Bandwidth (-3dB): 90MHz
Supply Voltage Range: 3V to 15V
Number of Circuits: 4
On-State Resistance Matching (ΔRon): 5Ω
Package: 14-SOIC (3.90mm Width)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

Analog signal multiplexing in audio processing chains.
Switching of sensor inputs in instrumentation systems.
Low-frequency RF signal path selection.
General-purpose analog signal routing in embedded systems.
