The TC74AC245, 640 are advanced high speed CMOS OCTAL
BUS TRANSCEIVERs fabricated with silicon gate and
double-layer metal wiring C2MOS technology.
They achieve the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
They are intended for two-way asynchronous communication
between data busses. The direction of data transmission is
determined by the level of the DIR input.
The enable input ( G ) can be used to disable the device so that
the busses are effectively isolated.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.

Note 1: Do not apply a signal to any bus terminal when it is in
the output mode. Damage may result.
Note 2: All floating (high impedance) bus terminals must have
their input levels fixed by means of pull up or pull down
resistors.

Note 1: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating
current consumption without load.
Average operating current can be obtained by the equation:
ICC (opr) = CPD·VCC·fIN·ICC/8 (per bit)
Note 2: For TC74AC245 only
Note 3: For TC74AC640 only
