Octal Bus Transceiver with 3-State Outputs

GENERAL DESCRIPTION

FEATURES

The 74HC245 is an 8-bit bus transceiver with 3-state

outputs. The supply voltage can accept any voltage

from 2.0V to 5.5V. The An and Bn are 8-bit data

input-output ports. DIR is the direction control input and

● Wide Operating Voltage Range: 2.0V to 5.5V

● +7.8mA/-7.8mA Output Current

● CMOS Low Power Consumption

● High Noise Immunity

��

OE is the output enable input.

● Octal Bus Interface with Bidirectional Translation

● 3-State Non-Inverting Outputs

When DIR is set high, it allows transmission from An to

Bn. When DIR is set low, it allows transmission from Bn

● -40℃ to +125℃ Operating Temperature Range

● Available in Green SOIC-20 and TSSOP-20

Packages

��

to An. OE can be used to make the outputs disabled

so that the buses are effectively isolated. The clamp

diodes of inputs allow the use of current limiting

resistors to connect inputs to the voltage exceeding

supply voltage.
