ADM101E, ADM3311E, ADM2209E vanguard line RS-232 transceivers developed most demanding applications requiring tiny, space-saving packages, current draw, (Electrostatic Discharge) protection ADM101E, ADM3311E, ADM2209E designed battery-operated, portable instruments such HPCs, PDAs, handsets; peripherals such printers modems; well cable modem set-top boxes desktop laptop PCs. ADM101E This world's smallest single driver/single receiver RS-232, been designed operate from single supply. highly efficient charge-pump voltage inverter generates on-chip supply, eliminating need negative power supply, which permits RS-232-compatible output levels developed using charge pump capacitors small ADM3311E Operating from single supply this three-driver/five-receiver RS-232 only features voltage inverter, voltage tripler that produce RS-232 output driver levels from supply. ADM3311E also features Green Idle, which reduces power consumption adjusting internal oscillator frequency when senses loads transmitter outputs, which ensures data transmission integrity. ADM2209E Operating from supply (and including dc-to-dc converter generate power rail), ADM2209E integrates complete serial ports single 38-pin TSSOP package. Even with total drivers receivers, ADM2209E will draw little standby mode. ADM2209E ideal ACPI-based because receivers remain active with standby supply when supply shuts down. ADM2209E will also handle speeds Kbps. following table shows main features ESD-protected ADM101E, ADM3311E, ADM2209E.
