description
The SN75LVDS86 FlatLink receiver contains three serial-in 7-bit parallel-out shift registers, a 7× clock
synthesizer, and four low-voltage differential signaling (LVDS) line receivers in a single integrated circuit. These
functions allow receipt of synchronous data from a compatible transmitter, such as the SN75LVDS81, ’83, ’84,
or ’85, over four balanced-pair conductors, and expansion to 21 bits of single-ended low-voltage TTL (LVTTL)
synchronous data at a lower transfer rate.
When receiving, the high-speed LVDS data is received and loaded into registers at seven times (7×) the LVDS
input clock (CLKIN) rate. The data is then unloaded to a 21-bit-wide LVTTL parallel bus at the CLKIN rate. A
phase-locked loop (PLL) clock synthesizer circuit generates a 7× clock for internal clocking and an output clock
for the expanded data. The SN75LVDS86 presents valid data on the falling edge of the output clock (CLKOUT).
The SN75LVDS86 requires only four line-termination resistors for the differential inputs and little or no control.
The data bus appears the same at the input to the transmitter and output of the receiver with the data
transmission transparent to the user. The only possible user intervention is the use of the shutdown/clear
(SHTDN) active-low input to inhibit the clock and shut off the LVDS receivers for lower power consumption. A
low level on this signal clears all internal registers to a low level.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

The LVDS receivers of the SN75LVDS86 include an open-circuit fail-safe design, such that when the inputs are
not connected to an LVDS driver, the receiver outputs go to a low level. This occurs even when the line is
differentially terminated at the receiver inputs.
The SN75LVDS86 is characterized for operation over ambient free-air temperatures of 0_C to 70_C.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
