Octal Bus Transceiver
transceiver fabricated with silicon gate C
bipolar schottky TTL while maintaining the CMOS low power
dissipation.
between data busses. The direction of data transmission is
determined by the level of the DIR input.
the busses are effectively isolated.
discharge.
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.
