6 Switches and Multiplexers Performance in Digital Signal Applications

For switches and multiplexers in use in digital signal applications, in addition to the signal switch specifications highlighted in Section 4, the following features also need to be considered:

Number of bits required to be switched. With TI's wide variety of signal switches, it is possible to switch between 1 to 32 bits at the same time with a single device. For instance, the LVC1G66 or CBT1G125 can be used to switch a single bit, while the CBTLV16211 is capable of switching 24 bits total in banks of 12. Or, by tying the adjacent enable pins together, it is possible to control 24 bits with one enable signal.
Special features. TI offers bus switches with special features, such as an integrated diode for single-component level shifting (CBTD), active clamps for undershoot protection (CBTK), Schottky-diode clamps for undershoot protection (CBTS), a bus-hold option (CBTH) for holding floating or unused I/O pins at valid logic levels, and an integrated-series-resistor option (CBTR) to reduce signal-reflection noise.

Table 6-1 summarizes the digital performance characteristics of TI signal switches from which generalities can be derived regarding switch-family performance. For exact parameters, refer to the respective data sheets.

(1) Data are based on data-sheet parameters for the parts tested for this application report. Refer to the respective data sheets for specific parameters and load conditions.

(2) t_pd is the same as t_PLH/t_PHL. The switch contributes no significant propagation delay other than the RC delay of the typical on-state resistance of the switch and the load capacitance when driven by an ideal voltage source (zero output impedance).

(3) t_ON is the same as t_PZL/t_PZH.

(4) t_OFF is the same as t_PLZ/t_PHZ.
