SEMICONDUCTOR TECHNICAL DATA LVX 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. • • • • • • • • LOW–VOLTAGE CMOS 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 DW SUFFIX 20–LEAD SOIC PACKAGE CASE 751D–04 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.
