SP320 Complete +5V-Only V.35 Interface with RS-232 V.28 Control Lines

The SP320 is a complete V.35 interface transceiver offering 3 drivers and 3 receivers of V.35, and 4 drivers and 4 receivers of RS-232 (V.28). A Sipex patented charge pump allows +5V only low power operation. RS-232 drivers and receivers are specified to operate at 120kbps, all V.35 drivers and rece.

SP320 Features

* 500mV of hysteresis margin to minimize the effects of noisy transmission lines. The inputs also have a 5kΩ resistor to ground; in an open circuit situation the input of the receiver will be forced low, committing the output to a logic high state. The input resistance will maintain 3kΩ-7kΩ over a ±15
