DESCRIPTION
The LX5212 is a nine-line active terminator for the SCSI parallel bus. This SCSI standard recommends active termination at both ends of the SCSI bus.
During disconnect mode, the LX5212 requires a meager 500nA of supply current while offering only 2.5pF of output capacitance. To enter this low-power mode, the disconnect pin can be left open (floating) or driven high, thereby disconnecting the terminating resistors and placing the internal low dropout regulator into low-power mode. In disconnect mode, each termination line presents a high impedance to the SCSI bus with the overall effect being to preserve high signal integrity and yield subsequent reliable, error-free communications.


KEY FEATURES
■ 2.5pF OUTPUT CAPACITANCE DURING DISCONNECT
■ 500nA SUPPLY CURRENT IN DISCONNECT MODE
■ 600µA SUPPLY CURRENT DURING NORMAL OPERATION
■ 30mA SINK CURRENT FOR ACTIVE NEGATION
■ LOGIC COMMAND DISCONNECTS ALL TERMINATION LINES
■ CURRENT LIMIT AND THERMAL PROTECTION
■ COMPATIBLE WITH SCSI 1, 2, 3, AND FAST 20 STANDARDS
■ HOT SWAP COMPATIBLE
■ CONSULT FACTORY FOR APPLICATION TEST REPORT: 5212TR
■ EVALUATION BOARD AVAILABLE
