SP233A General Description

The Sipex SP231A, SP232A and SP233A are enhanced versions of the Sipex SP231, SP232 and SP233 RS-232 line drivers/receivers. They are pin-for-pin replacements for these earlier versions and will operate in their sockets. Performance enhancements include 10V/s slew rate,120k bits per second guaranteed transmission rate, and increased drive current for longer and more flexible cable configurations. Ease of use enhancements include smaller, 0.1F charge pump capacitors, enhanced ESD protection, low power dissipation and overall ruggedized construction for commercial environments. The series is available in plastic and ceramic DIP and SOIC packages operating over the commercial, industrial and military temperature ranges.

SP233A Features

The Sipex SP231A, SP232A and SP233A are enhanced versions of the Sipex SP231, SP232 and SP233 RS-232 line drivers/receivers. They arepinfor-pin replacements for these earlier versions, will operate in their sockets with capacitors ranging from 0.1 to 100mF, either polarized or nonpolarized, and feature several improvements in both performance and ease of use. Performance enhancements include 10V/ms slew rate, 120k bits per second guaranteed transmission rate, and increased drive current for longer and more flexible cable configurations. Ease of useenhancementsincludesmaller,0.1mFchargepump capacitors, enhanced ESD protection, low power dissipation and overall ruggedized construction for commercial environments.

The SP232A, SP233A, SP310A and SP312A include charge pump voltage converters which allow them to operate from a single +5V supply. These converters convert the +5V input power to the ±10V needed to generate the RS-232 output levels. Both meet all EIA RS-232D and CCITT V.28 specifications.The SP231A has provisions for external V+supplies. With this power supplied externally, the current drain due to charge pump operation is
considerably reduced, typically to 400mA.

The SP310A provides identical features as the SP232A. The SP310A has a single control line which simultaneously shuts down the internal DC/DC converter and puts all transmitter and receiver outputs into a high impedance state. The SP312A is identical to the SP310A with separate tri-state
and shutdown control lines.

The SP231A is available in 14-pin plastic DIP,CERDIP and 16-pin SOIC packages for operation over commercial, industrial and military temperature ranges. The SP232A is available in 16-pin plastic DIP, SOIC and CERDIP

SP233A Typical Application

The driver outputs are protected against shorts to ground, other driver outputs, and V⁺or V^-.If the possibility exists that the outputs could be inadvertently connected to voltages higher than ±15V, then it is recommended that external protection be provided. For protection against voltages exceeding ±15V, two back-to-back zener diodes connected from each output to ground will clamp the outputs to an acceptable voltage level.
