SN75C08 Description
The SN75C08 is an input/output SCSI buffer with eight channels. One channel, REQ (request), is an open-drain driver that includes controlled rise and fall times to reduce crosstalk and RF emissions on the SCSI bus. The device also has one channel, ACK (acknowledge), that is a receiver that typically exhibits 600 mV of hysteresis and a 2.5-ns pulse filter to reject noise for bus reflections and/or other sources.
