The 74HC158 is a quad two-input multiplexer that features low power dissipation, inverting data path, and ESD protection. The device selects 4 bits of data from two sources and are controlled by a ...
The 74LVC257A is a quad two-input multiplexer with 5 V tolerant inputs/outputs and 3-state outputs. These 3-state outputs select 4 bits of data from two sources and are controlled by a common data ...
This circuit can be implemented with low-cost op amps, a multiple-channel two-input multiplexer (e.g., CD4053), a suitable ADC, and a few resistors. More easily, it drops into a Cypress PSoC1 part, ...
