Product Summary

The MC74HC245AN is an octal 3-state noninverting bus transcier. The MC74HC245AN inputs are compatible with standard CMOS outputs; with pull-up resistors, they are compatible with LSTTL outputs. The MC74HC245AN has an active-low Output Enable pin, which is used to place the I/O ports into high-impedance states.
