The CD54HC245, CD54HCT245, and CD74HC245,CD74HCT245 are high-speed octal three-state bidirectional transceivers intended for two-way asynchronous communication between data buses. They have high drive current outputs which enable high-speed operation while driving large bus capacitances. They provide the low power consumption of standard CMOS circuits with speeds and drive capabilities comparable to that of LSTTL circuits. The CD54HC245, CD54HCT245, CD74HC245 andCD74HCT245 allow data transmission of the B bus or from the B bus to the A bus. The logic level at the direction input(DIR) determines the direction. The output enable input (OE), when high, puts the I/O ports in the high-impedance state. The HC/HCT245 is similar in operation to the HC/HCT640and the HC/HCT643.
