Externally applied voltages, VCCB and VCCA, set the logic levels on either side of the device. A low-voltage logic signal present on the VCCA side of the device appears as a high-voltage logic signal on the VCCB side of the device, and vice-versa. The UM3202Q/3202A/3202H/3202V bidirectional level translator utilizes a transmission-gate based design to allow data translation in either direction (VCCA↔VCCB) on any single data line. The UM3202Q/3202A/3202H/3202V accepts VCCA from +1.65V to +3.6V and VCCB from +2.3V to +5.5V, making it ideal for data transfer between low-voltage ASICs / PLDs and higher voltage systems. The UM3202Q/3202A/3202H/3202V enters a three-state output mode to reduce supply current when output enable (OE) is low. The UM3202Q/3202A/3202H/3202V is designed so that the OE input circuit is supplied by VCCA. ±15kV ESD protection on the VCCB side for greater protection in applications that route signals externally. The UM3202Q/3202A/3202H/3202V is a dual level translator available in DFN8 1.70×1.35, QFN10 1.8×1.4, CSP8 1.9×0.9 and VSSOP8 packages. Applications Features SPI, MICROWIRE, and I 2C Level Translation Low-Voltage ASIC Level Translation Smart Card Readers Cell-Phone Cradles Portable POS Systems Portable Communication Devices Low-Cost Serial Interfaces Cell-Phones GPS Telecommunications Equipment Max Data Rates: 24Mbps (Push Pull), 2Mbps (Open Drain) Bidirectional Level Translation 1.65V to 3.6V on A Port and 2.3V to 5.5V on B Port (VCCA≤VCCB) ±15kV ESD Protection on B Port No Power-Supply Sequencing Required VCCA or VCCB can be Ramped First DFN8, QFN10, CSP8 and VSSOP8 Packages |
