Diodes Company (Diodes Incorporated) has launched 74LVC1G3157, a single-pole double-throw analog switch product designed for multiplexing of digital or analog signals. The low on-resistance of this switch solution can ensure high integrity when audio signal routing, so it is very suitable for mobile phones, tablets and e-readers as well as personal music players, handheld game consoles, satellite navigation and other audio equipment A wide range of advanced consumer electronics products.
The 74LVC1G3157 device operates at a 5V supply voltage and has a lower than 6? The on-state impedance can realize the routing of input audio signals, and even support routing output for low-power applications. Its typical off-state leakage current is 20nA, providing high isolation, allowing devices such as resistors or capacitors to switch into or out of the signal path for programmable filters or different gain configurations.
The 74LVC1G3157 device is designed for a power supply voltage range of 1.65V to 5.5V and can handle the signal amplitude between VCC and ground; its control input is up to 5.5V, without considering VCC and control pins, and has hysteresis characteristics to achieve more Slow input rise and fall times. The compact X2-DFN1410 package occupies only 1.4 mm2 circuit board space, allowing designers to use multiple components to route multiple signals, and its 0.5mm lead spacing can simplify circuit board assembly. This device is also available in SOT363 package type.
