What are the key features of SN75LVDT1422PAG?
- 14-channel LVDS transceiver compliant with EIA/TIA-644 differential interface standard for high-noise-immunity data links
- Full-duplex serializer/deserializer architecture enables simultaneous transmit and receive on the same differential pair set
- 64-pin PQFP package integrates all channel drivers and receivers to minimize board space in backplane and cable interface designs
What is SN75LVDT1422PAG used for?
The SN75LVDT1422PAG is used in test and measurement equipment, industrial automation controllers, and communications backplanes where 14-bit parallel data must be transmitted over cable or PCB traces at high speed with low electromagnetic emissions. Its EIA/TIA-644-compliant LVDS outputs provide differential signaling that reduces ground bounce and EMI compared to single-ended CMOS buses, making it suitable for point-to-point data links in noisy factory-floor environments.

Frequently Asked Questions
How many differential LVDS channels does SN75LVDT1422PAG support and what interface standard does it comply with?
The SN75LVDT1422PAG supports 14 differential driver channels compliant with the EIA-644 and TIA-644 LVDS standards. Each channel operates with differential output swings of approximately 350 mV, providing high noise immunity over twisted-pair cables or controlled-impedance PCB traces at data rates exceeding 100 MHz per channel.
Why is SN75LVDT1422PAG preferred over single-ended CMOS transceivers for long-cable industrial data links?
LVDS differential signaling of the SN75LVDT1422PAG rejects common-mode noise up to ±1 V on the cable, which is critical in factory environments with motor drives and switching power supplies generating significant EMI. Compared to 5 V CMOS single-ended buses, LVDS also consumes significantly less power per channel and supports cable lengths up to several meters at hundreds of Mbps without signal degradation.
What packaging does SN75LVDT1422PAG use and how does it simplify board layout for a 14-bit interface?
The SN75LVDT1422PAG is housed in a 64-pin PQFP package, which groups all 14 driver pairs and supporting control pins in a single component. This consolidation shortens the differential trace lengths from serializer outputs to connectors and simplifies impedance matching, compared to using multiple 4-channel LVDS buffer ICs that would require routing signals across a larger PCB area.
