http://www.union-ic.com Rev.06 Sep.2013 8 / 1 3 UM3202 Applications Information The UM3202Q/3202A/3202H can be used in level-tr anslation applications for interfacing devices or systems operating at different interface voltages with one another. The UM3202Q/3202A/3202H is ideal for use in applicat ion where an open-drain driver is connected to the data I/Os. The UM3202Q/3202A/3202H can also be used in applications where a push-pull driver is connected to the data I/Os, but the UM3302 might be a better option for such push-pull applications. Block Diagram The UM3202Q/3202A/3202H (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-kΩ pullup resistor to V CCA, and each B-port I/O has an internal 10-k Ω pullup resistor to VCCB. During a rising edge, the one- shot turns on the PMOS transi stors (PU1, PU2) for a short duration, which speeds up the low-to-high transition. Figure 1 Block Diagram of UM3202Q/3202A/3202H I/O Cell Input Driver Requirements The fall time (t fA, tfB) of a signal depends on the output impe dance of the external device driving the data I/Os of the UM3202Q/3202A/3202H. 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 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, V CCA≥ VCCB does not damage the device, so any power supply can be ramped up first. Enable and Disable The UM3202Q/3202A/3202H 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 th e user must allow for the one-shot circuitry to become operational after OE is taken high.
http://www.union-ic.com Rev.06 Sep.2013 9 / 1 3 UM3202 Pullup or Pulldown Resistors on I/O Lines Each A-port I/O has an internal 10-kΩ pullup resistor to VCCA, and each B-port I/O has an internal 10-kΩ pullup resistor to V CCB. If a smaller value of pullup resistor is required, an external resistor must be added from the I/O to VCCA or VCCB (in parallel with the internal 10-kΩ resistor). Test Circuits A. CL i n c l u d e s p r o b e a n d j i g c a p a c i t a n c e s . B. Waveform 1 is for an output with internal conditions such that the output is low, except when disabled by the output control. Waveform 2 is for an output with internal conditions such that the output is high, except when disabled by the output control. C. All input pulses are supplied by generators having the following characteristics: PRR≤100MHz, ZO=50Ω, dv/dt≥1V/ns. D. The outputs are measured one at a time, with one transition per measurement. E. TPLZ and TPHZ are the same as tdis. F. TPZL and TPZH are the same as ten. G. TPLH and TPHL are the same as tpd. H. VCCI is the VCC associated with the input port. I. VCCO is the VCC associated with the output port. J. All parameters and waveforms are not applicable to all devices. Figure 2 Load Circuits and Voltage Waveforms
