Features

  • an enhanced automatic powerdown function that powers down the on-chip power-supply and driver circuits. Automatic powerdown occurs when all receiver and transmitter inputs detect no signal transitions for a period of 30s. The ICL3238E automatically powers back up whenever it senses a transition on any transmitter or receiver input. The transmitter and logic inputs include active feedback resistors that retain the input state when driven to a valid logic level. Table 1 summarizes the features of.

Datasheet ICL3238E ±15kV ESD Protected, +3V to +5.5V, 10nA, 250kbps, RS-232 Transceiver with Enhanced Automatic Powerdown The ICL3238E contains 3.0V to 5.5V powered RS-232 transmitters/receivers that meet ElA/TIA-232 and V.28/V.24 specifications, even at VCC = 3.0V. It provides ±15kV ESD protection (IEC61000-4-2 Air Gap and Human Body Model) on transmitter outputs and receiver inputs (RS-232 pins). Targeted applications are cell phones, Palmtops, and data cables in which the low operational power consumption and even lower standby power consumption is critical. Efficient on-chip charge pumps coupled with manual and enhanced automatic powerdown functions reduce the standby supply current to a 10nA trickle.
