Each of the four multiplexers selects between two inputs, giving a 4 x 2:1 configuration in a single 16-SOIC package. Output drive is rated at 32 mA source and 64 mA sink — enough to drive a standard TTL load or a short PCB trace without a buffer. ## Board-fit and sourcing posture The surface-mount assembly matches reflow profiles common to lead-free solder processes.","metaTitle":"Infineon CY74FCT157CTSOC Multiplexer, 4 x 2:1, 16-SOIC","metaDescription":"Active-production Infineon CY74FCT157CTSOC quad 2-input multiplexer, 4 x 2:1 circuit, 4.75-5.25V supply, -40 to 85°C, 16-SOIC.
