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 auto-power-down enabled, the device is automatically activated when a valid signal is applied to any receiver input. Typical applications are notebooks, PDAs, smartphones, hand-held equipment, palmtop computers, peripherals, battery-powered equipment, and printers.Description
The STLV3243EB device consists of 3 drivers, 5 receivers and a dual charge-pump circuit. All transmitter outputs and receiver inputs are protected ±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. 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. 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. Device summary
