TB5R2 3.3V 四路 PECL 线路接收器
These quad differential receivers accept digital data overbalanced transmission lines. They translate differential input logic levels to TTL output logic levels.
The TB5R1 is a pin- and function-compatible replacement for the Agere systems BRF1A and BRF2A; it includes 3-kV HBM and 2-kV CDM ESD protection.
The TB5R2 is a pin- and function-compatible replacement for the Agere systems BRS2A and BRS2B and incorporates a 125-mV receiver input offset, preferred state output, 3-kV HBM and 2-kV CDM ESD protection. The TB5R2 preferred state feature places the high state when the inputs are open, shorted to ground, or shorted to the power supply.
The power-down loading characteristics of the receiver input circuit are approximately 8 k
relative to the power supplies; hence they do not load the transmission line when the circuit is powered down
