Overview
The SN65LVELT23DGKR is a low-power dual LVPECL/LVDS to LVTTL translator device manufactured by Texas Instruments. This device is designed to translate differential LVPECL (Low-Voltage Positive Emitter-Coupled Logic) or LVDS (Low-Voltage Differential Signaling) inputs to LVTTL (Low-Voltage Transistor-Transistor Logic) outputs. It features internal circuitry to maintain inputs at VCC/2 when left open, ensuring stable operation even with floating inputs.
The device is available in industry-standard SOIC-8 and VSSOP-8 packages, making it versatile for various applications. It supports clock frequencies up to 180 MHz and has a typical propagation delay of 2 ns, making it suitable for high-speed data and clock transmission.
