SP312A 5伏，单向RS-232驱动器／接收器，关断启动功能
The SP233A / SP310A / SP312A devices are a family of line driver and receiver pairs that meets the specifications of RS-232 and V.28 serial protocols. The devices are pin-to-pin compatible with popular industry standard pinouts. The SP233A / SP310A / SP312A offer 120kbps data rate under load, small ceramic type 0.1μF charge pump capacitors and overall ruggedness for comercial appli- cations. Features include Exar's BiCMOS design allowing for low power operation without sacrificing performance. These devices are available in plastic DIP and SOIC Wide packages operating over the commercial and industrial temperature ranges.
