74LVCV2G66

Overvoltage tolerant bilateral switch

12. Application information

Use the 74LVCV2G66 to reduce component count and footprint in low-power portable

applications.

Typical ‘66’ devices do not have low-power enable inputs causing a high

ΔI

CC. To reduce

power consumption in portable (battery) applications, a current limiting resistor is used.

(see Figure 20a). The low-power enable inputs of the 74LVCV2G66 have much lower

ΔI

CC, eliminating the necessity of the current limiting resistor (see Figure 20b).
