Bidirectional Logic Level Translator
ADG3304
Figure 1.
GENERAL DESCRIPTION
The ADG3304 is a bidirectional logic level translator that contains four bidirectional channels. It can be used in multivoltage
digital system applications, such as data transfer, between a low
voltage digital signal processing controller and a higher voltage
device using SPI and MICROWIRE interfaces. The internal
architecture allows the device to perform bidirectional logic
level translation without an additional signal to set the direction
in which the translation takes place.
The voltage applied to VCCA sets the logic levels on the A side of
the device, while VCCY sets the levels on the Y side. For proper
operation, VCCA must always be less than VCCY. The VCCA-compatible logic signals applied to the A side of the device appear as
VCCY-compatible levels on the Y side. Similarly, VCCY-compatible
logic levels applied to the Y side of the device appear as VCCAcompatible logic levels on the A side.
Rev. E
The enable pin (EN) provides three-state operation on both the
A side and the Y side pins. When the EN pin is pulled low, the
terminals on both sides of the device are in the high impedance
state. The EN pin is referred to the VCCA supply voltage and
driven high for normal operation.
The ADG3304 is available in compact 14-lead TSSOP, 12-ball
WLCSP, and 20-lead LFCSP. It is guaranteed to operate over
the 1.15 V to 5.5 V supply voltage range.

ADG3304
THEORY OF OPERATION
The ADG3304 level translator allows the level shifting necessary
for data transfer in a system where multiple supply voltages are
used. The device requires two supplies, VCCA and VCCY (VCCA ≤
VCCY). These supplies set the logic levels on each side of the
device. When driving the A pins, the device translates the VCCAcompatible logic levels to VCCY-compatible logic levels available
at the Y pins. Similarly, because the device is capable of
bidirectional translation, when driving the Y pins, the VCCYcompatible logic levels are translated to VCCA-compatible logic
levels available at the A pins. When EN = 0, Pin A1 to Pin A4
and Pin Y1 to Pin Y4 are three-stated. When EN is driven high,
the ADG3304 goes into normal operation mode and performs
level translation.
LEVEL TRANSLATOR ARCHITECTURE
The ADG3304 consists of four bidirectional channels. Each
channel can translate logic levels in either the A→Y or the Y→A
direction. It uses a one-shot accelerator architecture, which
ensures excellent switching characteristics. Figure 39 shows a
simplified block diagram of a bidirectional channel.

N
The ADG3304 level translator is designed to drive CMOScompatible loads. If current-driving capability is required, it is
recommended to use buffers between the ADG3304 outputs
and the load.
ENABLE OPERATION
The ADG3304 provides three-state operation at the A and Y
I/O pins by using the enable pin (EN), as shown in Table 5.

High impedance state.
In normal operation, the ADG3304 performs level translation.
While EN = 0, the ADG3304 enters into three-state mode. In this
mode, the current consumption from both the VCCA and VCCY
supplies is reduced, allowing the user to save power, which is
critical, especially on battery-operated systems. The EN input pin
can be driven with either VCCA-compatible or VCCY-compatible
logic levels.

To ensure correct operation of the ADG3304, the circuit that

output impedance of less than or equal to 150 Ω and a
minimum peak current driving capability of 36 mA.

Figure 39. Simplified Block Diagram of an ADG3304 Channel
The logic level translation in the A→Y direction is performed
using a level translator (U1) and an inverter (U2), while the
translation in the Y→A direction is performed using Inverter U3
and Inverter U4. The one-shot generator detects a rising or
falling edge present on either the A side or the Y side of the
channel. It sends a short pulse that turns on the PMOS transistors
(T1 to T2) for a rising edge, or the NMOS transistors (T3 to T4)
for a falling edge. This charges/discharges the capacitive load
faster, which results in faster rise and fall times.
For proper operation of the ADG3304, the voltage applied to
the VCCA must be less than or equal to the voltage applied to VCCY.
To meet this condition, the recommended power-up sequence
is VCCY first and then VCCA. The ADG3304 operates properly
only after both supply voltages reach their nominal values. It is
not recommended to use the part in a system where, during
power-up, VCCA can be greater than VCCY due to a significant
increase in the current taken from the VCCA supply. For
optimum performance, the VCCA pin and VCCY pin should be
decoupled to GND as close as possible to the device.
The inputs of the unused channels (A or Y) should be tied to
their corresponding VCC rail (VCCA or VCCY) or to GND.

DATA RATE
The maximum data rate at which the device is guaranteed to
operate is a function of the VCCA and VCCY supply voltage
combination and the load capacitance. It is given by the
maximum frequency of a square wave that can be applied to the
device, which meets the VOH and VOL levels at the output and
does not exceed the maximum junction temperature (see the
Absolute Maximum Ratings section). Table 6 shows the
guaranteed data rates at which the ADG3304 can operate in
both directions (A→Y or Y→A level translation) for various VCCA
and VCCY supply combinations.

ADG3304
APPLICATIONS INFORMATION
The ADG3304 is designed for digital circuits that operate at
different supply voltages; therefore, logic level translation is
required. The lower voltage logic signals are connected to the
A pins, and the higher voltage logic signals are connected to the
Y pins. The ADG3304 can provide level translation in both
directions from A→Y or Y→A on all four channels, eliminating
the need for a level translator IC for each direction. The internal
architecture allows the ADG3304 to perform bidirectional level
translation without an additional signal to set the direction in
which the translation is made. It also allows simultaneous data
flow in both directions on the same part, for example, when two
channels translate in A→Y direction while the other two translate
in Y→A direction. This simplifies the design by eliminating the
timing requirements for the direction signal and reducing the
number of ICs used for level translation.

Figure 40 shows an application where two microprocessors
operating at 1.8 V and 3.3 V, respectively, can transfer data
simultaneously using two full-duplex serial links, TX1/RX1
and TX2/RX2.

Figure 40. 1.8 V to 3.3 V Level Translation Circuit on
Two Full-Duplex Serial Links
When the application requires level translation between a microprocessor and multiple peripheral devices, the ADG3304 I/O
pins can be three-stated by setting EN = 0. This feature allows
the ADG3304 to share the data buses with other devices without
causing contention issues. Figure 41 shows an application where
a 1.8 V microprocessor is connected to a 3.3 V peripheral
device using the three-state feature.
As with any high speed digital IC, the printed circuit board
layout is important for the overall performance of the circuit.
Care should be taken to ensure proper power supply bypass and
return paths for the high speed signals. Each VCC pin (VCCA and
VCCY) should be bypassed using low effective series resistance
(ESR) and effective series inductance (ESI) capacitors placed as
close as possible to the VCCA pin and the VCCY pin. The parasitic
inductance of the high speed signal track may cause significant
overshoot. This effect can be reduced by keeping the length of
the tracks as short as possible. A solid copper plane for the
return path (GND) is also recommended.
