Key Features
- 7-bit parallel-to-serial converter with LVDS differential outputs per EIA-644 standard enables high-speed, noise-immune serial data transmission over twisted-pair cables
- Differential Schmitt trigger inputs provide hysteresis for reliable switching in noisy environments and support connection to LVDS sources with varying common-mode voltages
- 56-pin TSSOP package with 4 integrated functions in a single IC reduces component count for compact flat-panel display interface and high-speed serial link designs
Applications
SN75LVDS81DGG is designed for flat-panel display interfaces and high-speed serial data links where parallel pixel data must be serialized and transmitted over differential LVDS lines per EIA-644. Its 7-bit serialization with differential outputs makes it a key component in LCD panel drivers, digital video transmission systems, and point-to-point serial link interfaces that require EMI-reduced differential signaling. The 56-pin TSSOP format suits it for compact display controller boards and industrial video equipment where board space is limited and signal integrity at multi-hundred-MHz data rates is required.

Frequently Asked Questions
Which interface standard does SN75LVDS81DGG comply with and what cable length does it support?
SN75LVDS81DGG conforms to the EIA-644 LVDS standard, which specifies differential signal levels of 247 mV to 454 mV across a 100 Ω termination resistor, enabling reliable data transmission over twisted-pair cables at distances of several meters depending on data rate. At typical LCD interface data rates of 100 MHz to 400 MHz, signal integrity is maintained for cable lengths of 0.5 m to 2 m with properly terminated 100 Ω differential lines.
How does SN75LVDS81DGG's Schmitt trigger input improve noise immunity at the receiver interface?
SN75LVDS81DGG uses differential Schmitt trigger inputs with built-in hysteresis, which prevents spurious toggling caused by slow-rising input signals or common-mode noise on the differential line. The Schmitt trigger threshold ensures that the input must swing through a defined voltage band before changing state, making the device tolerant of signal reflections and common-mode voltage variations that occur in long cable and backplane differential signal environments.
For flat-panel display designs, how many pixel bits can SN75LVDS81DGG serialize per clock cycle?
SN75LVDS81DGG serializes 7 parallel data bits per differential output channel per clock cycle, which aligns with the LVDS flat-panel interface standard where RGB pixel data is transmitted as groups of 7 bits per LVDS lane. A full 24-bit RGB pixel requires multiple SN75LVDS81DGG devices, with each handling one 7-bit color sub-channel, enabling high-resolution display interfaces operating at pixel clock rates from 25 MHz up to several hundred MHz depending on supply and process conditions.
