SN74LVC2G66DCTR TI Analog Switches, Multiplexers, Demultiplexers

The SN74LVC2G66DCTR is a dual bilateral analog switch from Texas Instruments, part of the LVC family, designed for 1.65V to 5.5V VCC operation. The device features two independent single-pole single-throw (SPST) analog switches with low ON-state resistance of 10 Ω typical at 4.5V. Each switch section has its own enable-input control, and a high-level voltage applied to the control turns on the associated switch section. The device can handle both analog and digital signals with amplitudes of up to 5.5V (peak) in either direction, supporting rail-to-rail input/output. Key specifications include a -3dB bandwidth of 300MHz, propagation delay of 0.8 ns max at 3.3V, high degree of linearity, and ultra-low power consumption. Latch-up performance exceeds 100 mA per JESD 78, Class II. Housed in an 8-pin SM8 (DCT) package, it operates over -40°C to 85°C. Applications include signal gating, chopping, modulation/demodulation (modems), and signal multiplexing for analog-to-digital and digital-to-analog conversion systems.
