Product Summary
The CD54HC245F3A is a high-speed octal three-state bidirectional transceiver, which is intended for two-way asynchronous communication between data buses. It has high drive current outputs which enable high-speed operation while driving large bus capacitances. The CD54HC245F3A provides the low power consumption of standard CMOS circuits with speeds and drive capabilities comparable to that of LSTTL circuits.
