mc74lvx4245 http://onsemi.com 6 dual supply octal translating transceiver the 74lvx4245 is a is a dual?supply device well capable of bidirectional signal voltage translation. this level shifting ability provides an excellent interface between low voltage cpu local bus and a standard 5.0 v i/o bus. the device control inputs can be controlled by either the low voltage cpu and core logic or a bus arbitrator with 5.0 v i/o levels. the lvx4245 is ideal for mixed voltage applications such as notebook computers using a 3.3 v cpu and 5.0 v peripheral devices. applications: mixed mode dual supply interface solutions the lvx4245 is designed to solve 3.0 v / 5.0 v interfaces when cmos devices cannot tolerate i/o levels above their applied v cc . if an i/o pin of a 3.0 v device is driven by a 5.0 v device, the p?channel transistor in the 3.0 v device will conduct ? causing current flow from the i/o bus to the 3.0 v power supply. the result may be destruction of the 3.0 v device through latchup effects. a current limiting resistor may be used to prevent destruction, but it causes speed degradation and needless power dissipation. a better solution is provided in the lvx4245. it provides two different output levels that easily handle the dual voltage interface. the a port is a dedicated 5.0 v port; the b port is a dedicated 3.0 v port. since the lvx4245 is a `245 transceiver, the user may either use it for bidirectional or unidirectional applications. the center 20 pins are configured to match a `245 pinout. this enables the user to easily replace this level shifter with a 3.0 v `245 device without additional layout work or re? manufacture of the circuit board (when both buses are 3.0 v). figure 3. 3.3v/5v interface block diagram lvx4245 v ccb v cca lvx4245 v ccb v cca eisa - isa - mca (5v i/o levels) low voltage cpu local bus powering up the lvx4245 when powering up the lvx4245, please note that if the v ccb pin is powered?up well in advance of the v cca pin, several milliamps of either i cca or i ccb current will result. if the v cca pin is powered?up in advance of the v ccb pin then only nanoamps of icc current will result. in actuality the v ccb can be powered aslightlyo before the v cca without the current penalty, but this asetup timeo is dependent on the power?up ramp rate of the v cc pins. with a ramp rate of approximately 50 mv/ns (50v/ s) a 25 ns setup time was observed (v ccb before v cca ). with a 7.0 v/ s rate, the setup time was about 140ns. when all is said and done, the safest powerup strategy is to simply power v cca before v ccb . one more note: if the v ccb ramp rate is faster than the v cca ramp rate then power problems might still occur, even if the v cca powerup began prior to the v ccb powerup.
