MOTOROLA SEMICONDUCTOR TECHNICAL DATA 18ĆBit Switchable Active SCSIĆ2 Bus Terminator (110Ω) With Voltage Regulator and Inverted Disconnect MCCS142238 The MCCS142238™ is a precision 18-bit switchable active SCSI-2 bus terminator with an on-board 2.85V regulator. When the Disconnect pin is HIGH according to the truth table below, the MCCS142238 provides 110Ω ±5% precision resistor pull-ups to a 2.85V reference for termination of 18-bits in a SCSI-2 standard bus system interface. When the Disconnect pin is LOW, the device outputs are in the high impedance state on all 18 bits. The regulator is also turned off, greatly reducing standby power. Even with no Termpwr applied, the outputs remain in the high impedance state.
