STLV3243EB ± 15 kV ESD protected 2.3 to 5.5 V, 400 kbps, RS-232 transceiver with auto-power-down Features ■ ESD protection for RS-232 I/O pins: – ± 8 kV IEC 1000-4-2 contact discharge – ± 15 kV human body model ■ 1 mA supply current achieved when in autopower-down ■ 250 kbps minimum guaranteed data rate ■ Guaranteed 6 V/ms slew rate range ■ Guaranteed mouse drive ability ■ 0.1 µF external capacitors ■ Meet EIA/TIA-562 specifications ■ Available in Flip-Chip28 package ) s t( c u d e t e l o s ) s t( b O - l o s c u d o r c u d P e et Typical applications are notebooks, PDAs, smartphones, hand-held equipment, palmtop computers, peripherals, battery-powered equipment, and printers. l o bs The STLV3243EB device consists of 3 drivers, 5 receivers and a dual charge-pump circuit. All transmitter outputs and receiver inputs are protected up to ±8 kV USING IEC 1000-4-2 contact discharge and ±15 kV using the human body model. The receiver R2 is always active to implement a wake-up feature for serial port. The device is guaranteed to run at data rates of 250 kbps while maintaining RS-562 output levels. P e et ) s t( auto-power-down enabled, the device is automatically activated when a valid signal is applied to any receiver input. Description ro o r P Flip-Chip28 O ) s ( t c u d o r eP The auto-power-down feature operates when FORCEON is low and FORCEOFF is high. During this operation mode, if the device does not sense a valid RS-562 signal, the driver outputs are disabled. If FORCEOFF is set low, both drivers and receivers (expert R2B) are shut off, and supply current is reduced to 1 µA. Disconnecting the serial port or turning off the peripheral drives causes the auto-power-down condition to occur. Ob t e ol s b O Auto-power-down can be disabled when FORCEON and FORCEOFF are high, and this should be done when driving a serial mouse. With Table 1.
