Overview
The DS91C176TMA-NS is a half-duplex multipoint Low-Voltage Differential Signaling (M-LVDS) transceiver produced by Texas Instruments, although it may be distributed through various channels including National Semiconductor. This component is designed for applications requiring low power dissipation, low noise, and high data rates. It is particularly optimized for use in multipoint networks, such as clock distribution in AdvancedTCA (ATCA) and microTCA (uTCA) systems.
