SN65LVDS84AQDGG

The SN75LVDS84A and SN65LVDS84AQ FlatLink transmitters contains three 7-bit parallel-load serial-out shift registers, and four low-voltage differential signaling (LVDS) line drivers in a single integrated circuit. These functions allow 21 bits of single-ended LVTTL data to be synchronously transmitted over 3 balanced-pair conductors for receipt by a compatible receiver, such as the SN75LVDS82 or SN75LVDS86/86A. The ’LVDS84A requires no external components 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(s). The only user intervention is the possible use of the shutdown/clear (SHTDN) active-low input to inhibit the clock and shut off the LVDS output drivers for lower power consumption. A low-level on this signal clears all internal registers to a low level. The SN75LVDS84A is characterized for operation over ambient free-air temperatures of 0℃ to 70℃. The SN65LVDS84AQ is characterized for operation over the full Automotive temperature range of -40℃ to 125℃.
