4-Bit Bidirectional Voltage-Level Translator for
Open-Drain and Push-Pull Application

UM3204UE TSSOP14
General Description
The UM3204 is quad 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 UM3204 bidirectional level translator utilizes a transmission-gate based design to allow data
translation in either direction (VCCA↔VCCB) on any single data line. The UM3204 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 UM3204 enters a three-state output mode to reduce supply current when output enable (OE)
is low. The UM3204 is designed so that the OE input circuit is supplied by VCCA. ±5kV ESD
protection on the VCCB side for greater protection in applications that route signals externally. The
UM3204 is a quad level translator available in CSP12 1.9×1.4, QFN14 3.5×3.5 and TSSOP14
packages.

UM3204
Applications Information
The UM3204 can be used in level-translation applications for interfacing devices or systems
operating at different interface voltages with one another. The UM3204 is ideal for use in
application where an open-drain driver is connected to the data I/Os. The UM3204 can also be
used in applications where a push-pull driver is connected to the data I/Os, but the UM3304 might
be a better option for such push-pull applications.
Block Diagram
The UM3204 (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
pull-up resistor to VCCA, and each B-port I/O has an internal 10-kΩ pull-up resistor to VCCB.
During a rising edge, the one-shot turns on the PMOS transistors (PU1, PU2) for a short duration,
which speed 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 UM3204. 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 UM3204 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.

UM3204
Pull-up or Pull-down Resistors on I/O Lines
Each A-port I/O has an internal 10-kΩ pull-up resistor to VCCA, and each B-port I/O has an
internal 10-kΩ 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 10-kΩ
resistor).

C. All input pulses are supplied by generators having the following characteristics: PRR≤100MHz, Z O=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.
