________________________________________________________________________ http://www.union-ic.com rev.06 may.2012 8/13 UM3204 applications information the UM3204 can be used in level-translation applications for interfacing devices or systems operating at different interface voltages with one another. the UM3204 is ideal for use in application where an open-drain driver is connect ed to the data i/os. the UM3204 can also be used in applications where a push-pull driver is connected to the data i/os, but the um3304 might be a better option for such push-pull applications. block diagram the UM3204 (block diagram see figure 1) does not require a direction-control signal to control the direction of data flow from a to b or from b to a. each a-port i/o has an internal 10-k ? pull-up resistor to v cca , and each b-port i/o has an internal 10-k ? pull-up resistor to v ccb . during a rising edge, the one-shot turns on the pmos transistors (pu1, pu2) for a short duration, which speeds up the low-to-high transition. figure 1 block diagram of UM3204 i/o cell input driver requirements the fall time (t fa , t fb ) of a signal depends on the output impedance of the external device driving the data i/os of the UM3204. similarly, the t phl and the maximum date rates also depend on the output impedance of the external driver. the values for t fa , t fb , t phl , and the maximum date rates in the data sheet assume that the output impedan ce of the external driver is less than 50 ? . power up during operation, ensure that v cca v ccb at all times. during power-up sequencing, v cca v ccb does not damage the device, so any power supply can be ramped up first. enable and disable the UM3204 has an oe input that is used to di sable the device by setting oe = low, which places all i/os in the high-impedance (hi-z) state. the disable time (tdis) indicates the delay between the time when oe goes low and when the outputs actua lly get disabled (hi-z). the enable time (ten) indicates the amount of time the user must allow for the one-shot circuitry to become operational after oe is taken high.
