ATTENUATOR AND POWER PIN DIODES UM2100 Series PIN diodes are designed for transmit/receive switch and attenuator applications in HF band (2-30MHz) and below. As series configured switches, these long lifetime (25μs typical) diodes can control up to 2.5 kW, CW in a 50 ohm system. In HF band, insertion loss is less than 0.25dB and isolation is greater than 32dB (off-state). The UM2100 series offers the lowest distortion performance in both the transmit and receive modes. Less than 50 mA forward bias is requires to obtain an IP3 of 60 dBm at 300 kHz with 1 watt per tone. The forward biased resistance/reactance vs. frequency characteristics are flat down to 10 kHz. The capacitance vs. reverse bias voltage characteristic is fla... |

2-Bit Bidirectional Voltage Level Translator The UM2102S allows bidirectional voltage translations between 1.5V and 5V without the use of a direction pin. The UM2012S is not a bus buffer which provides both level translation and physically isolates the capacitance to either side of the bus when both sides are connected. The UM2102S only isolates both sides when the VREF is connected to GND. Pull-up resistors are required on both sides to provide the logic HIGH levels on the translator’s bus. The size of these pull-up resistors depends on the system. The device is designed to work with Standard-mode, Fast-mode and Fast-mode Plus I2C-bus devices in addition to SMBus devices. The maximum frequency is dependent on the RC time constant, bu... |

High ESD +5V RS-232 Transceivers The UM207/208/211/213 are enhanced transceivers intended for use in RS-232 and V.28 serial communication and are particularly suited for those applications where ±12V is not available. These devices feature very low power consumption and +5V single supply operation making them ideal for space-constrained applications. With integrated charge pump circuitry and small 0.1µF charge pump capacitors, these devices can fully meet RS-232 voltage levels. A slow rate limited transmitter circuit improves data integrity. The receiver features hysteresis to greatly improve noise rejection. The UM211 and UM213 feature a low power shutdown mode, which reduces power supply drain to 1µA. The UM213 includes t... |
