DESCRIPTION
The M74HCT245 is an advanced high-speed
CMOS OCTAL BUS TRANSCEIVER (3-STATE)
fabricated with silicon gate C2MOS technology.
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
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.
