5V, 400KBPS, RS-232 TRANSCEIVER WITH AUTO-POWERDOWN s s s s s s s 1µA SUPPLY CURRENT ACHIEVED WHEN IN AUTO-POWERDOWN 250Kbps MINIMUM GUARANTEED DATA RATE GUARANTEED 6V/µs SLEW RATE RANGE GUARANTEED MOUSE DRIVEABILITY 0.
1µF EXTERNAL CAPACITORS MEET EIA/TIA-232 SPECIFICATIONS DOWN TO 3V AVAILABLE IN SO-28, SSOP-28 AND TSSOP28 SOP DESCRIPTION The ST3243 device consists of 3 drivers, 5 receivers and a dual charge-pump circuit.
The device meets the requirements of EIA/TIA and V.
28/V.
24 comunication standards providing high data rate capability.
The receiver R2 is always active to implement a wake-up feature for serial port.
The ST3243 has a proprietary low-dropout transmitter output stage enabling true RS-232 performance from a 3.
0V to 5.
5V supply with a dual charge pump.
The device is guaranteed to run at data rates of 250kbps while maintaining RS-232 output levels.
The Auto-powerdown feature functions when FORCEON is low and FORCEOFF is high.
During this mode of operat...
