General Description
The UM3202Q/3202A/3202H/3202V is ±15kV dual channel ESD-protected level translator
provide the level shifting necessary to allow data transfer in a multi-voltage system. 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.

UM3202
Applications Information
The UM3202Q/3202A/3202H/3202V can be used in level-translation applications for interfacing
devices or systems operating at different interface voltages with one another. The
UM3202Q/3202A/3202H/3202V is ideal for use in application where an open-drain driver is
connected to the data I/Os. The UM3202Q/3202A/3202H/3202V 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/3202V (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 10kΩ pull-up resistor to VCCA, and each B-port I/O has an internal
10kΩ pull-up resistor to VCCB. During a rising edge, the one-shot turns on the PMOS transistors
(PU1, PU2) for a short duration, that speeds up the low-to-high transition.

Input Driver Requirements
The fall time (tfA, tfB) of a signal depends on the output impedance of the external device driving
the data I/Os of the UM3202Q/3202A/3202H/3202V. 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 VCCA≤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 UM3202Q/3202A/3202H/3202V 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.

UM3202
Pull-up or Pull-down Resistors on I/O Lines
Each A-port I/O has an internal 10kΩ pull-up resistor to VCCA, and each B-port I/O has an internal
10kΩ pull-up resistor to VCCB. If a smaller value of pull-up resistor is required, an external resistor
must be added from the I/O to VCCA or VCCB (in parallel with the internal 10kΩ resistor).

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.
