Description

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.
