(ESD)-protected, high-speed transceivers for RS-485 communication that contain one driver and one receiver. These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open, shorted or idle. This means that the receiver output will be logic high if all transmitters on a terminated bus are disabled (high impedance).

When the UM3243 does not sense a valid signal level on their receiver inputs, the on-board power supply and drivers shut down. The UM3243 requires only 4×0.1μF capacitors in 3.3V operation, and can operate from input voltages ranging from +3.0V to +5.5V. It is ideal for 3.3V-only systems, mixed 3.3V and 5.0V systems, or 5.0V-only systems that require true RS-232 performance. +3.3V 0.1µF C1 0.1µF + C2 0.1µF + TTL/ CMOS INPUTS Applications Battery-Powered Systems PDAs Notebooks Laptops Palmtop PCs Hand-Held Equipments + VCC C1+ C1C2+ V+ UM3243 V- C2T1IN T1OUT T2IN T2OUT T3IN T3OUT + C3 0.1µF + C4 0.1µF RS-232 OUTPUTS R2OUTB TTL/ CMOS OUTPUTS R1OUT R1IN R2OUT 5k R2IN R3OUT 5k R3IN 5k RS- 232 INPUTS R4IN R4OUT 5k R5IN R5OUT 5k FORCEON VCC TO POWER MANAGEMENT UNIT FORCEOFF INVALID GND UM3243 Typical Operating Circuit www.union-ic.com Rev.09 Mar.2015 17 Union Semiconductor Product Selection Guide Interface and System Interconnect 2/4-Bit Bidirectional Voltage-Level Translator for Open-Drain and Push-Pull Applications UM3202/UM3204 Key Features The UM3202/3204 is 2/4 channel ESD-protected level translator provide the level shifting necessary to allow data transfer in a multi-voltage system.
