http://www.union-ic.com Rev.02 Jan.2015 8/13 UM3301 Applications Information The UM3301B/UM3301DA ESD protected level translator provide s level shifting necessary to allow data transfer in a multi -voltage system. Externally applied voltages, V CCA and VCCB set the logic levels on either side of device. A low voltage signal present on V CCA side of the device appears as a high voltage logic signal on the VCCB side of the device, and vice-versa. Block Diagram The UM3301B/UM3301DA (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. In a dc state, the output drivers of the UM3301B/UM3301DA can maintain a high or low, but are designed to be weak, so that they can be overdri ven by an external driver when data on the bus starts flowing towards the opposite direction. The output one shot detects rising or falling edges on the A or B ports. During a rising edge, the one shot turns on the PMOS transistors (T1, T3) for a short duration, which speeds up the low-to-high transition. Similarly, during a falling edge, the one shot turns on the NMOS transistors (T2, T4) for a short duration, which speeds up the high-to-low transition.

http://www.union-ic.com Rev.02 Jan.2015 9/13 UM3301 Input Driver Requirements Typical IIN vs VIN characteristics of the UM3301B/UM3301DA are shown in Figure 2. For proper operation, the device driving the data I/Os of the UM3301B/UM3301DA must have drive strength of at least ±2 mA. IIN VIN VT/4kΩ -(VD-VT)/4kΩ A: VT is the input threshold voltage of the UM3301B/UM3301DA (typical VCCI/2) B: VD is the supply voltage of the external driver. Figure 2 Typical IIN vs VIN Curve 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. The UM3301B/UM3301DA has circuitry that disables all output ports when either VCC is switched off (VCCA/B = 0 V). Enable and Disable The UM3301B/UM3301DA 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 when OE goes low and when the outputs ac tually 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. Pullup or Pulldown Resistors on I/O Lines The UM3301B/UM3301DA is designed to dri ve ca pacitive loads of up to 70pF. The output drivers of the UM3301B/UM3301DA have low dc drive strength. External pullup or pulldown resistors need to be higher than 50kΩ. For the same reason, the UM3301B/UM3301DA should not be used in open-drain system, such as I2C or 1-wire system.
