1 2-Bit Bidirectional oltage-level Tralator for Open-Drain and Push-Pull Application Q DFN A QFN H CSP General Description The Q/3202A/3202H is ±15k dual channel ESD-protected level tralator provide the level shifting necessary to allow data trafer in a multi-voltage system. Externally applied voltages, CCB and CCA, set the logic levels on either side of the device. A low-voltage logic signal present on the CCA side of the device appears as a high-voltage logic signal on the CCB side of the device, and vice-versa. The Q/3202A/3202H bidirectional level tralator utilizes a tramission-gate based design to allow data tralation in either direction ( CCA CCB ) on any single data line. The Q/3202A/3202H accepts CCA from to +3.6 and CCB from +2.3 to +5.5, making it ideal for data trafer between low-voltage ASICs / PLDs and higher voltage systems. The Q/3202A/3202H enters a three-state output mode to reduce supply current when output enable (OE) is low. The Q/3202A/3202H is designed so that the OE input circuit is supplied by CCA. ±15k ESD protection on the CCB side for greater protection in applicatio that route signals externally. The Q is a dual level tralator available in DFN , the A is a dual level tralator available in QFN , and the H is a dual level tralator available in CSP package.

9 Applicatio Information The Q/3202A/3202H can be used in level-tralation applicatio for interfacing devices or systems operating at different interface voltages with one another. The Q/3202A/3202H is ideal for use in application where an open-drain driver is connected to the data I/Os. The Q/3202A/3202H can also be used in applicatio where a push-pull driver is connected to the data I/Os, but the UM3302 might be a better option for such push-pull applicatio. Block Diagram The Q/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 CCA, and each B-port I/O has an internal 10-kΩ pullup resistor to CCB. During a rising edge, the one-shot tur on the PMOS traistors (PU1, PU2) for a short duration, which speeds up the low-to-high traition. CCA CCB PU1 ONE- SHORT BLOCK ONE- SHORT BLOCK PU2 GATE BIAS I/O A_ N I/O B_ Input Driver Requirements Figure 1 Block Diagram of Q/3202A/3202H I/O Cell 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 Q/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, eure that CCA CCB at all times. During power-up sequencing, CCA CCB does not damage the device, so any power supply can be ramped up first. Enable and Disable The Q/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 the user must allow for the one-shot circuitry to become operational after OE is taken high. Rev.07 Apr /14

10 Pullup or Pulldown Resistors on I/O Lines Each A-port I/O has an internal 10-kΩ pullup resistor to CCA, and each B-port I/O has an internal 10-kΩ pullup resistor to CCB. If a smaller value of pullup resistor is required, an external resistor must be added from the I/O to CCA or CCB (in parallel with the internal 10-kΩ resistor).
