Features

•

The TC7MH245FK is an advanced high speed CMOS octal bus

It achieves the high speed operation similar to equivalent

It is intended for two-way asynchronous communication

The enable input (G) can be used to disable the device so that

All inputs are equipped with protection circuits against static

High speed: t

Low power dissipation: I

High noise immunity: V

Balanced propagation delays: t

Wide operating voltage range: V

Low noise: V

Pin and function compatible with 74ALS245

Note: Do not apply a signal to any bus terminal when it is in the output mode. Damage may result.

All floating (high impedance) bus terminals must have their input levels fixed by means of pull up or pull down

resistors.

A parasitic diode is formed between the bus and V

interface 5 V to 3 V systems directly.
