SEMICONDUCTOR TECHNICAL DATA  
EIA–232–E and CCITT V.28  
These devices are silicon gate CMOS ICs that combine both the transmitter  
and receiver to fulfill the electrical specifications of EIA Standard 232–E and  
CCITT V.28. The drivers feature true TTL input compatibility, slew rate limiting  
outputs, 300 Ω power–off source impedance, and output typically switching to  
within 25% of the supply rails. The receivers can handle up to ± 25 V while  
presenting 3 to 7 kΩ impedance. Hysteresis in the receivers aid in the reception  
of noisy signals. By combining both drivers and receivers in a single CMOS  
chip, these devices provide efficient, low–power solutions for both EIA–232–E  
and V.28 applications.

ESD protection on IC devices that have their pins accessi-  
ble to the outside world is essential. High static voltages ap-  
plied 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 will usually  
occur through the internal ESD protection diodes. The key to  
protecting the IC is to shunt as much of the energy to ground  
as possible before it enters the IC. Figure 4 shows a tech-  
nique 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 – C3. This scheme has provided protection to  
the interface part up to ± 10 kV, using the human body model  
test.
