UPD4726

Features:

• Conforms to EIA/TIA-32-E (old RS-232C) Standards
• +5 V single power supply
• A standby mode can be set by making the standby pin low to reduce the power dissipation.  At this time, the driver outputs go into a high-impedance state.
• Two receiver circuits can operate as inverters without a hysteresis width even in the standby mode.  The remaining five receiver circuits are fixed to the high level.
