SCSI driver
c. Single-ended signal input characteristics
All SCSI units (including both the receivers and disable drivers) shall meet the following
electrical signal characteristics during power-on:
1) V (Low-level input voltage) = 1.0 VDC Max (True signal)
IL
2) V (High-level input voltage) = 1.9 VDC Min (False signal)
IH
(Low-level input current) = +/-20 µA if V
3) I
IL
(High-level input current) = +/-20 µA if V
4) I
IH
5) Minimum input hysteresis = 0.3 VDC
The transient leakage current, which may be generated during physical insertion of an SCSI
device (for example, at the ESD protection circuit), shall be the exponentially decreasing
current to be less than the following specifications value:
1) I . (High-level input current peak during active insertion except for initial 10 ns) = +1.5 mA
IH HP
where, V
(transient current duration to 10% of peak value) = 20 µs maximum
2) T
