Nexperia 74LVC1G66GW Bilateral Analogue Switch SPST TSSOP

The Nexperia 74LVC1G66GW is a single-pole single-throw (SPST) bilateral analogue switch in a surface-mount TSSOP package, supporting a supply voltage range of 1.65 V to 5.5 V.

Overview

The device provides two input/output terminals, Y and Z, and an active HIGH enable input, E, which controls the signal path. When the enable pin is set to LOW, the analogue switch is turned off, providing reliable isolation. The enable input includes Schmitt-trigger action, which makes the circuit tolerant of slower input rise and fall times. The wide supply voltage range allows operation in both 3.3 V and 5 V systems.

Key Features

• Very low ON resistance, with 6.2 Ω typical and 23 Ω maximum, to minimise signal attenuation and power loss
• Integrated ESD protection against electrostatic discharge during handling and assembly
• High noise immunity for electrically noisy environments
• CMOS technology with low power consumption
• TTL interface compatibility at 3.3 V for connection with legacy TTL and low-voltage logic families
• Operating temperature range of -40 °C to +125 °C

Packaging and Integration

The surface-mount TSSOP package is compact and designed for automated assembly processes. Its extended operating temperature range supports demanding industrial applications.
