SEMICONDUCTOR TECHNICAL DATA

Octal Bus Transceiver

With 5V-Tolerant Inputs

The MC74LVX245 is an advanced high speed CMOS octal bus

transceiver.

It is intended for two–way asynchronous communication between data

buses. The direction of data transmission is determined by the level of the

T/R input. The output enable pin (OE) can be used to disable the device,

so that the buses are effectively isolated.

All inputs are equipped with protection circuits against static discharge.

•

High Speed: tPD = 4.7ns (Typ) at VCC = 3.3V

Low Power Dissipation: ICC = 4µA (Max) at TA = 25°C

Power Down Protection Provided on Inputs

Balanced Propagation Delays

Low Noise: VOLP = 0.8V (Max)

Pin and Function Compatible with Other Standard Logic Families

Latchup Performance Exceeds 300mA

ESD Performance: HBM > 2000V; Machine Model > 200V

APPLICATION NOTES

1. Do not force a signal on an I/O pin when it is an active output, damage may

occur.

2. All floating (high impedence) input or I/O pins must be fixed by means of

pull up or pull down resistors or bus terminator ICs.

3. A parasitic diode is formed between the bus and VCC terminals. Therefore,

the LVX245 cannot be used to interface 5V to 3V systems directly.
