________________General Description
The MAX3093E/MAX3094E are rugged, low-power,
quad, RS-422/RS-485 receivers featuring electrostatic
discharge (ESD) protection for use in harsh environments. All receiver inputs are protected to ±15kV using
IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 10004-2 Contact Discharge, and ±15kV using the Human
Body Model. The MAX3093E operates from a +5V supply, while the MAX3094E operates from a +3.3V supply.
Receiver propagation delays are guaranteed to within
±8ns of a predetermined value, thereby ensuring
device-to-device matching across production lots.
The devices feature a 1nA low-power shutdown mode
in which the receiver outputs are high impedance.
When active, these receivers have a fail-safe feature
that guarantees a logic-high output if the input is open
circuit. They also have a quarter-unit-load input impedance that allows 128 receivers on a bus.
The MAX3093E/MAX3094E are pin-compatible, lowpower upgrades to the industry-standard ’34C86. They
are available in space-saving TSSOP, narrow SO, and
PDIP packages.

_______________Detailed Description
±15kV ESD Protection
As with all Maxim devices, ESD-protection structures are
incorporated on all pins to protect against ESDs encountered during handling and assembly. The
MAX3093E/MAX3094E receiver inputs have extra
protection against static electricity found in normal
operation. Maxim’s engineers have developed stateof-the-art structures to protect these pins against ±15kV
ESD without damage. After an ESD event, the
MAX3093E/MAX3094E continue working without latchup.
ESD protection can be tested in several ways. The
receiver inputs are characterized for protection to the
following:
• ±15kV using the Human Body Model
• ±8kV using the Contact Discharge Method specified
in IEC 1000-4-2 (formerly IEC 801-2)
• ±15kV using the Air-Gap Method specified in
IEC 1000-4-2 (formerly IEC 801-2)
ESD Test Conditions
ESD performance depends on a number of conditions.
Contact Maxim for a reliability report that documents
test setup, methodology, and results.
Human Body Model
Figure 4a shows the Human Body Model, and Figure
4b shows the current waveform it generates when discharged into a low impedance. This model consists of a
100pF capacitor charged to the ESD voltage of interest,
which is then discharged into the device through a
1.5kΩ resistor.
IEC 1000-4-2
Since January 1996, all equipment manufactured and/or
sold in the European community has been required to
meet the stringent IEC 1000-4-2 specification. The IEC
1000-4-2 standard covers ESD testing and performance
of finished equipment; it does not specifically refer to integrated circuits. The MAX3093E/MAX3094E help you
design equipment that meets Level 4 (the highest level) of
IEC 1000-4-2, without additional ESD-protection components.
The main difference between tests done using the
Human Body Model and IEC 1000-4-2 is higher peak
current in IEC 1000-4-2. Because series resistance is
lower in the IEC 1000-4-2 ESD test model (Figure 5a), the
ESD-withstand voltage measured to this standard is generally lower than that measured using the Human Body
Model. Figure 5b shows the current waveform for the
±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test.
The Air-Gap test involves approaching the device with a
charge probe. The Contact-Discharge method connects
the probe to the device before the probe is energized.
Machine Model
The Machine Model for ESD testing uses a 200pF storage capacitor and zero-discharge resistance. It mimics
the stress caused by handling during manufacturing
and assembly. All pins (not just RS-485 inputs) require
this protection during manufacturing. Therefore, the
Machine Model is less relevant to the I/O ports than are
the Human Body Model and IEC 1000-4-2.
Low-Power Shutdown Mode
The function tables show the functionality of the enable
inputs. The MAX3093E/MAX3094E enter shutdown
when ENAC and ENBD are low. In shutdown, all outputs go high impedance and the devices typically draw
less than 1nA. The devices exit shutdown by taking
either ENAC or ENBD high. The typical shutdown exit
time is 600ns.

Applications Information
Propagation-Delay Matching
The MAX3093E/MAX3094E exhibit propagation delays
that are closely matched from one device to another,
even between devices from different production lots. This
feature allows multiple data lines to receive data and
clock signals with minimal skewing with respect to each
other. The MAX3093E receiver propagation delays are
trimmed to a predetermined value ±8ns, while the
MAX3094E delays are trimmed to a predetermined value
±10ns.
128 Receivers on the Bus
The standard RS-485 input impedance is 12kΩ (one-
unit load). The standard RS-485 transmitter can drive
32 unit loads. The MAX3093E/MAX3094E present a 1/4unit-load input impedance (48kΩ), which allows up to
128 receivers on a bus. Any combination of these RS485 receivers with a total of 32-unit loads can be connected to the same bus.
Fail-Safe Implementation
The MAX3093E/MAX3094E receiver inputs guarantee a
logic high output when the inputs are open circuit (no
termination resistor used). This occurs when the transmitter is removed from the bus or when all transmitter
outputs are high impedance. However, when the line is
terminated and the transmitters are disabled, the differential voltage between the A and B inputs falls below
the ±200mV RS-485 sensitivity threshold. Consequently, the outputs become undefined. To maintain a failsafe receiver output while using a terminating resistor,
input A must be biased at least 200mV above input B.
The resistor-divider network shown in Figure 6 is recommended.
