HEC4066BT,118

Analog Switches, Multiplexers, Demultiplexers Overview

The HEC4066BT,118 is a quad bilateral switch manufactured by Nexperia, distributed under the NXP USA Inc. brand. It features four independent SPST switches in a TSSOP14 package. The device operates within a supply voltage range of 2 V to 10 V. Key electrical parameters include a maximum on-resistance of 128 Ohms, a maximum propagation delay of 150 ns, and a maximum turn-off time of 225 ns. It supports an extended industrial temperature range from -40 °C to +125 °C and includes ESD protection compliant with JESD22 standards.
