DESCRIPTION

The M74HC245 is an advanced high-speed

CMOS OCTAL BUS TRANSCEIVER (3-STATE)

fabricated with silicon gate C

This IC is intended for two-way asynchronous

communication between data buses, and the

direction of data transmission is determined by

DIR input. The enable input G can be used to

PIN CONNECTION AND IEC LOGIC SYMBOLS

ORDER CODES

disable the device so that the buses are effectively

isolated.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.

All floating bus terminals during High Z State must

be held HIGH or LOW.
