The MC54/74HC245A is identical in pinout to the LS245. The device
inputs are compatible with standard CMOS outputs; with pullup resistors,
they are compatible with LSTTL outputs.
The HC245A is a 3–state noninverting transceiver that is used for 2–way
asynchronous communication between data buses. The device has an
active–low Output Enable pin, which is used to place the I/O ports into
high–impedance states. The Direction control determines whether data
flows from A to B or from B to A.

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high–impedance circuit. For proper operation, Vin and
Vout should be constrained to the
range GND (Vin or Vout) VCC.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or VCC).
Unused outputs must be left open.

* Maximum Ratings are those values beyond which damage to the device may occur.
Functional operation should be restricted to the Recommended Operating Conditions.
