SIPEX SP385ACA-L

The SP385A offers +3.3V operation for EIA-562 and EIA-232 applications. The SP385A maintains the same performance features offered in its predecessors. The SP385A is available in plastic SOIC or SSOP packages operating over the commercial and industrial temperature ranges. The SP385A is pin compatible to the LTC1385 EIA-562 transceiver, except the drivers in the SP385A can only be disabled with the ON/OFF pin.

• It is a pin-for-pin alternative for the SP310A and will operate in the same socket with capacitors ranging from 0.1μF to 10μF, either polarized or non–polarized, in +3V supplies.
• 120kbps guaranteed transmission rate.
• Increased drive current for longer and more flexible cable configurations.
• Low power dissipation and overall ruggedized construction for commercial and industrial environments.
• Includes a shutdown feature that tri-states the drivers and the receivers.
• Includes a charge pump voltage converter which allows it to operate from a single +3.3V or +5V supply. These converters double the Vcc voltage input in order to generate the EIA-232 or EIA562 output levels.
• For +5V operation, the driver outputs adhere to all EIA-232D and CCITT V.28 specifications. While at +3.3V operation, the outputs adhere to EIA-562 specifications.
• Due to efficient charge pump design, the charge pump levels and the driver outputs are less noisy than other 3V EIA-232 transceivers.
• 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.
• Available in 18-pin plastic SOIC and 20-pin plastic SSOP packages for operation over commercial and industrial temperature ranges.
• Ideal for +3.3V battery applications requiring low power operation.
• The charge pump strength allows the drivers to provide ±4.0V signals, plenty for typical EIA-232 applications since the EIA-232 receivers have input sensitivity levels of less than ±3V.
