Abstract
An ECL-to-TTL translator circuit for converting ECL logic level signals to TTL logic level signals includes an active pull-down circuit (120), a high level voltage clamping circuit (122), and ground bounce protection circuit (124) so as to provide a higher speed of operation with minimal power dissipation and a significant reduction in ground bounce noise. The ground bounce protection circuit is formed of a voltage-independent current source, a reference resistor (R15), and a switching transistor (Q15).
