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 = 4A (Max) at TA = 25C 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.
