Product Overview
The SN10KHT5578DWR from Texas Instruments is a high-performance 8-bit bus transceiver designed for bidirectional asynchronous communication between 10KH ECL and TTL logic families. Housed in a 24-pin SOIC package, this device features dual supply voltages (VCC = 5.0V for TTL, VEE = -5.2V for ECL) and offers propagation delays as low as 3.5 ns. It is ideal for mixed-signal environments requiring high-speed data transfer with minimal skew.
