High Speed, High Performance +5V
RS-232 Transceivers
General Description
Features
The SP213EH device is a high speed enhanced multichannel RS-232 line transceivers with improved electrical
performance and is a superior drop-in replacement to our
previous versions as well as popular industry standards. The
SP213EH features very low power CMOS construction and
MaxLinear-patented (5,306,954) on-board charge pump
circuitry that generates the ±10V RS-232 voltage levels using
0.1µF charge pump capacitors. The SP213EH device
features a low-power shutdown mode, which reduces power
supply drain to 1µA. Enhancements include a higher
transmission rate of 1Mbps, a lower power supply current at
3mA typical (no load), and superior ESD performance. The
ESD tolerance has been improved to over ±15kV for both
Human Body Model and IEC61000-4-2 Air Discharge test
methods.

SP213EH High Speed, High Performance +5V RS-232 Transceivers Data Sheet
Description
Description
As in the original RS-232 multi-channel products, the
SP213EH high speed multi–channel RS-232 line
transceiver provides a variety of configurations to fit most
designs, especially high speed applications where ±12V is
not available. The SP213EH is a superior high speed dropin replacement to our previous versions as well as popular
industry standards.
All devices in this series feature low–power CMOS
construction and MaxLinear's–proprietary on-board charge
pump circuitry to generate the RS-232 signal voltages. The
ability to use 0.1µF charge pump capacitors saves board
space and reduces production costs. The devices in this
series provide different driver / receiver combinations to
match any application requirement.
The SP213EH models features a low–power shutdown
mode, which reduces power supply drain current to 1µA.
The SP213EH includes a Wake-Up function which keeps
two receivers active in the shutdown mode, unless disabled
by the EN pin.
The family is available in SSOP (shrink) small outline
packages. Devices can be specified for commercial (0˚C to
+70˚C) and industrial / extended (–40˚C to +85˚C)
operating temperatures.
Theory Of Operation
The SP213EH device is made of three basic circuit blocks:
■
■
■
Transmitter / driver
Receiver
The MaxLinear proprietary charge pump
Each model within the series incorporates variations of
these circuits to achieve the desired configuration and
performance.
circuits to ground without degradation in reliability. The
drivers of the SP213EH can be tri–stated by using the
SHUTDOWN function.
In the "power-off" state, the output impedance will remain
greater than 300Ω, again satisfying the RS-232
specifications. Should the input of the driver be left open,
an internal 400kΩ pull-up resistor to VCC forces the input
high, thus committing the output to a low state. The
transition of the output from high to low also meets the
monotonicity requirements of the standard.
Receivers
The high performance receivers of the SP213EH device
can accept input signals at a typical data rate or 500kbps.
The receivers convert RS-232 level input signals to
inverted TTL level signals. Since the input is usually from a
transmission line where long cable lengths and system
interference can degrade the signal, the inputs have a
typical hysteresis margin of 500mV. This ensures that the
receiver is virtually immune to noisy transmission lines.
Should an input be left unconnected, a 5kΩ pull-down
resistor to ground will commit the output of the receiver to a
high state.
Shutdown Mode
The SP213EH features a control input which will disable
the device and reduce power supply current to less than
10µA, making the parts ideal for battery-powered systems.
In the "shutdown" mode, the receivers and transmitters will
both be tri-stated. The V+ output of the charge pump will
discharge to VCC and the V- output will discharge to
ground.
For complete shutdown to occur and the 10µA power drain
to be realized, the following conditions must be met:
Transmitter / Drivers
SP213EH:
The drivers of this series can maintain a typical data rate of
1Mbps. This superior RS-232 data transmission rate
makes the SP213EH series an ideal match for many
designs in personal computer peripherals and LAN
applications that demand high speed performance.

0V must be applied top the SD pin
The drivers are inverting transmitters, which accept either
TTL or CMOS inputs and output the RS-232 signals with an
inverted sense relative to the input logic levels. The
transmitter outputs are protected against infinite short–
