High-Speed CMOS Logic Octal-Bus Transceiver,

Three-State, Non-Inverting

November 1997 - Revised May 2003

Features

Description

• Buffered Inputs

The CD54HC245, CD54HCT245, and CD74HC245,

CD74HCT245 are high-speed octal three-state bidirectional

• Three-State Outputs

• Bus Line Driving Capability

[ /Title

(CD54

HC245

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.

• Typical Propagation Delay (A to B, B to A) 9ns at V

= 5V, C = 15pF, T = 25 C

• Wide Operating Temperature Range . . . -55 C to 125 C

• Balanced Propagation Delay and Transition Times

(DIR) determines the direction. The output enable input

(OE), when high, puts the I/O ports in the high-impedance

state.

• Signiﬁcant Power Reduction Compared to LSTTL

Logic ICs

The HC/HCT245 is similar in operation to the HC/HCT640

and the HC/HCT643.
