Frequently Asked Questions
What power supply voltage is required to operate the transceivers?
They can operate from a single 5-V power supply.
Does this device support high data transfer speeds and skew limits?
Yes, the SN75ALS170A variant supports FAST-20 SCSI and has up to 5 ns maximum skew.
How does the device handle direction control for its channels?
It features independent direction controls for each channel, and drivers/receivers use internal enables for function as a direction control.
Is this transciever suitable for noisy or long bus line applications?
Yes, it is designed for multipoint transmission on long bus lines in noisy environments and offers wide positive and negative common-mode voltage ranges.
