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.
