http://www.union-ic.com Rev.08 Dec.2014 10/15 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 UM 3204 is ideal for use in application where an open -drain driver is connected to the data I/Os. The UM 3204 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 se e 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 -kΩ pull-up resistor to V CCA, and each B -port I/O has an internal 10 -kΩ 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 speed up the low-to-high transition. ONE- SHORT BLOCK ONE- SHORT BLOCK GATE BIAS N PU1 PU2 VCCA VCCB I/O VA_ I/O VB_ Figure 1 Block Diagram of UM3204 I/O Cell Input Driver Requirements The fall time (t fA, tfB) of a signal depends on the output impedance of the external device driving the data I/Os of the UM 3204. Similarly, the tPHL and the maximum date rates also depend on the output impedance of the external driver. The values for tfA, tfB, tPHL, and the maximum date rates in the data sheet assume that the output impedance of the external driver is less than 50Ω. Power Up During operation, ensure that V CCA≤VCCB at all times. During power-up sequencing, VCCA≥ VCCB 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 disable 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 actually 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.
http://www.union-ic.com Rev.08 Dec.2014 11/15 UM3204 Pull-up or Pull-down Resistors on I/O Lines Each A -port I/O has an internal 10 -kΩ pull-up resistor to V CCA, and each B -port I/O has an internal 10 -kΩ pull-up resistor to V CCB. If a smaller value of pull -up resistor is required, an external resistor must be added from the I/O to V CCA or VCCB (in parallel with the internal 10 -kΩ resistor).
