# EIA–232–E and CCITT V.28
The MC145583 is a CMOS transceiver composed of three drivers and five
receivers that fulfills the electrical specifications of EIA–232–E, EIA–562, and
CCITT V.28 while operating from a single + 3.3 or + 5.0 V power supply. This
transceiver is a high–performance, low–power consumption device that is
equipped with a standby function.
A voltage tripler and inverter converts the + 3.3 V to ± 8.8 V, or a voltage
doubler and inverter converts the + 5.0 V to ± 8.8 V. This is accomplished
through an on–chip 40 kHz oscillator and five inexpensive external capacitors.
Drivers:
• ± 5 V Minimum Output Swing at 3.3 or 5.0 V Power Supply
• 300 Ω Power–Off Impedance
• Output Current Limiting
• Three–State Outputs During Standby Mode
Receivers:
• ± 25 V Input Range
• 3 to 7 kΩ Input Impedance
• 0.8 V Hysteresis for Enhanced Noise Immunity
• Three–State Outputs During Standby Mode
Ring Monitor Circuit:
• Invert the Input Level on Rx1 to Logic Output Level on RIMON at Standby

Storage Temperature Range
This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, precautions must be taken to avoid applications of
any voltage higher than maximum rated voltages to this high–impedance circuit. For proper
operation, it is recommended that the voltage
at the DI and DO pins be constrained to the
range GND ≤ VDI ≤ VCC and GND ≤ VDO
≤ VCC. Also, the voltage at the Rx pin should
be constrained to (VSS – 15 V) ≤ VRx1 – Rx5
≤ (VDD + 15 V), and Tx should be constrained
to VSS ≤ VTx1 – Tx3 ≤ VDD.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., GND or
VCC for DI, and GND for Rx).

MOTOROLA
driver and receiver output pins become high–impedance
state. In this condition, supply current ICC is below 5 µA (typ).
PIN DESCRIPTIONS
VCC
Digital Power Supply (Pin 27)
This digital supply pin is connected to the logic power supply. This pin should have a not less than 0.33 µF capacitor
GND.
GND
Ground (Pin 2)
Ground return pin is typically connected to the signal
ground pin of the EIA–232–E connector (Pin 7) as well as to
the logic power supply ground.
VDD
Positive Power Supply (Pin 23)
This is the positive output of the on–chip voltage tripler and
the positive power supply input of the driver/receiver sections
of the device. This pin requires an external storage capacitor
to filter the 50% duty cycle voltage generated by the charge
pump.
VSS
Negative Power Supply (Pin 5)
This is the negative output of the on–chip voltage tripler/inverter and the negative power supply input of the driver/ receiver sections of the device. This pin requires an external
storage capacitor to filter the 50% duty cycle voltage generated by the charge pump.
RIMON
Ring Monitor Circuit (Pin 4)
The Ring Monitor Circuit will convert the input level on Rx1
pin at standby mode and output on the RIMON pin.
STB
Standby Mode (Pin 6)
The device enters the standby mode while this pin is connected to the logic high level. During the standby mode,
C5+, C5–, C2+, C2–, C1+, C1–
Voltage Tripler and Inverter (Pins 1, 3, 28, 26, 25, 24)
These are the connections to the internal voltage tripler
and inverter, which generate the VDD and VSS voltages.
Rx1, Rx2, Rx3, Rx4, Rx5
Receive Data Inputs (Pins 7, 8, 9, 11, 13)
These are the EIA–232–E receive signal inputs. A voltage
between + 3 and + 25 V is decoded as a space, and causes
the corresponding DO pin to swing to GND (0 V). A voltage
between – 3 and – 25 V is decoded as a mark, and causes
the DO pin to swing up to VCC.
DO1, DO2, DO3, DO4, DO5
Data Outputs (Pins 22, 21, 20, 18, 16)
These are the receiver digital output pins, which swing
from VCC to GND. Output level of these pins is high impedance while in standby mode.
DI1, DI2, DI3
Data Inputs (Pins 19, 17, 15)
These are the high impedance digital input pins to the
drivers. Input voltage levels on these pins must be between
VCC and GND.
Tx1, Tx2, Tx3
Transmit Data Output (Pins 10, 12, 14)
These are the EIA–232–E transmit signal output pins,
which swing toward VDD and VSS. A logic 1 at a DI input
causes the corresponding Tx output to swing toward VSS.
The actual levels and slew rate achieved will depend on the
output loading (RL /CL ).
The minimum output impedance is 300 Ω when turned off.

ESD PROTECTION
ESD protection on IC devices that have their pins accessible to the outside world is essential. High static voltages
applied to the pins when someone touches them either
directly or indirectly can cause damage to gate oxides and
transistor junctions by coupling a portion of the energy from
the I/O pin to the power supply buses of the IC. This coupling
MMBZ15VDLT1 x 8
will usually occur through the internal ESD protection diodes
which are designed to do just that. The key to protecting the
IC is to shunt as much of the energy to ground as possible
before it enters the IC. Figure 1 shows a technique which will
clamp the ESD voltage at approximately ± 15 V using the
MMBZ15VDLT1. Any residual voltage which appears on the
supply pins is shunted to ground through the capacitors C1
and C2.
