Overview
The DS90LV048A device, produced by Texas Instruments, is a quad CMOS flow-through differential line receiver. It is designed for applications that require ultra-low power dissipation and support high data rates. This device utilizes Low Voltage Differential Signaling (LVDS) technology to handle data rates exceeding 400 Mbps (200 MHz). The DS90LV048A accepts low voltage differential input signals (typically 350 mV) and translates them to 3-V CMOS output levels. It features a flow-through pinout, which simplifies PCB layout, and supports TRI-STATE outputs for multiplexing. The device also includes input fail-safe mechanisms for open, shorted, and terminated input conditions, ensuring a stable HIGH output state in all fail-safe scenarios.
