CD74HC245M96 Datasheet PDF - TI

●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 and CD74HCT245 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/HCT640 and the HC/HCT643.
