The ADM3311E is a three-driver/five-receiver product designed to fully meet the EIA-232 standard while operating with a single +2.7 V to +3.6 V power supply. The device features an on-board, charge pump, dc-to-dc converter, eliminating the need for dual power supplies. This dc-to-dc converter contains a voltage tripler and voltage inverter, which internally generates positive and negative supplies from the input +3 V power supply. The dc-to-dc converter operates in Green Idle Mode, whereby the charge pump oscillator is gated on and off to maintain the out-put voltage at ±7.25 V under varying load conditions. This minimizes the power consumption and makes these products ideal for battery-powered portable devices.
The ADM3311E is suitable for operation in harsh electrical environments and contains ESD protection up to ±15 kV on all I-O lines. The ADM3311E contains three drivers and five receivers and is intended for serial port applications on notebook/laptop computers.
A shutdown facility is also provided that reduces the power consumption to 3μW. While in shutdown, one receiver remains active, thereby allowing monitoring of peripheral devices. This
feature allows the device to be shut down until a peripheral device begins communication. The active receiver can alert the processor, which can then take the ADM3311E out of the shutdown mode. The ADM3311E is fabricated using CMOS technology for minimal power consumption. It features a high level of over-voltage protection and latch-up immunity. The ADM3311E is packaged in a 28-lead SSOP/TSSOP package.
