SN74LVC1G3157DBVR Description

The SN74LVC1G3157DBVR from Texas Instruments is a high-performance, single-pole double-throw (SPDT) analog switch designed for precision signal routing in low-voltage applications. Packaged in a compact SOT23-6 form factor, this device operates over a wide supply voltage range of 1.65V to 5.5V, making it suitable for mixed-voltage systems. With an ultra-low on-state resistance (Ron) of 15Ω (max) and minimal channel-to-channel matching (ΔRon) of 100mΩ, it ensures minimal signal distortion and high fidelity in analog or digital signal paths. The switch also boasts a -3dB bandwidth of 340MHz, enabling high-speed signal switching with fast transition times (Ton/Toff: 5.7ns/3.8ns). Its low leakage current (1µA max) and low charge injection (7pC) further enhance performance in sensitive applications.
