RS-485 differential transceiver

The SN75LBC184 is the first '176 standard footprint RS-485 differential transceiver to offer integrated transient voltage protection. It, and its companion device, the SN65LBC184, provide significant protection from large over-voltage transients on the bus pins that can be caused by secondary effects of a lightning strike or power system switching disturbances.

These devices are well-suited for electrically noisy environments requiring large over-voltage and common mode swing protection. Typical applications include industrial equipment, alarm systems, telecommunications and computers.

The devices are available now from Texas Instruments and authorized distributors.
SN65LBC184 8-pin DIP and SOIC $2.72
SN75LBC184 8-pin DIP and SOIC $2.44

Suggested resale pricing in U.S. dollars in 1K quantity.

Features
Transient voltage suppression Provides protection from large noise transients to reduce down time
On-chip integrated solution Minimizes cost and printed board-space requirement
Controlled driver slew rates Provides reduced EMI and improved data ransmission at 250 Kbps over further unterminated cable runs and longer stub lengths
Half unit load Allows up to 64 similiar devices connected on a bus

A/D converters

The TLV1544 and TLV1548 are low-power, low-voltage, 10-bit serial A/D converters that can be connected directly to DSPs and microprocessors without external components.

These devices operate from a wide range of single-supply voltages (2.7-V to 5.5-V) and offer software programmable power-down mode supply current.

Both devices feature a simple direct-connection serial interface to either DSPs or microprocessor. These signals provide direct four-wire SPI™ compatible interface to the serial port of a host microprocessor or DSP. When interfaced with a TMS320 DSP, an additional frame sync input is used to indicate the start of a serial data frame.

The TLV1544 features an analog input mux that lets the user select among four different analog inputs and three internally generated self-test voltage levels. The TLV1548 lets the user select among eight analog inputs and the same three internally generated self-test voltage levels.
TLV1544CD 16-pin SOIC $3.28

TLV1548CDBLE 20-pin TSSOP $3.64
TLV1548IDBLE 20-pin TSSOP $4.13

FlatLink transmitter/receivers

TI has introduced the industry's first family of 3.3-V transmitter/receiver devices satisfying the emerging LVDS (Low Voltage Differential Signaling) data interface standard.

These FlatLink devices were developed for the transfer of display data and control signals from the video display processor of a portable computer to its flat panel display.

Addressing market needs for low power, high speed and reduced noise emissions, these devices offer small differential voltage swings resulting in a narrow, high bandwidth interface with minimal EMI.

The new FlatLink devices can be used to improve the performance of wide parallel single-ended synchronous data connections. Typical applications are laptop computers and networking point-to-point switch interconnects.The SN75LVDS81 FlatLink transmitter features four 7-bit parallel-load serial-out shift registers, a 7X clock synthesizer and five LVDS line drivers. These functions allow up to 28 bits of single-ended LVTTL data to be synchronously transmitted over five balanced-pair conductors for receipt by a compatible receiver, the SN75LVDS82. The 3-V operation offers improved performance over current market 5-V LVDS solutions.

Both devices are available now from TI and authorized distributors.
SN75LVDS81 56-pin TSSOP $6
SN75LVDS82 56-pin TSSOP $6

Suggested resale pricing in U.S. dollars in 1K quantity.
