GENERAL DESCRIPTION
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 tri-
pler 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 3
μ
W. 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.
