The LM55122/LM75122 are triple line receivers designed for digital data transmission with line impedances from 50n to 500n. Each receiver has one input with built·in hysteresis which provides a large noise margin. The other Inputs on each receiver are in a standard TTL configuration. The LM55122/LM75122 are compatible with standard TTL logic and supply volta.
• Built-in input threshold hysteresis
• High speed ... typical propagation delay time
20 ns
• Independent channel strobes
• Input gating increases application flexibility
• Single 5.0V supply operation
• Fanout to 10 series 54174 standard loads
• Plug-in replacement for the SN55122 and the
8T14
