descriptionThe SN75971B SCSI differential converter-data is a
9-channel RS-485 transceiver. When used in conjunc-
tion with its companion control transceiver, the
SN75970B, the resulting chip set provides the superior
electrical performance of differential SCSI from a
single-ended SCSI bus or controller. A 16-bit
Ultra-SCSI (or Fast-20) SCSI bus can be implemented
with just three devices (two data and one control) in the
space efficient, 56-pin, shrink small-outline package
(SSOP) or thin shink small outline package (TSSOP)
and a few external components. An 8-bit SCSI bus
requires only one data and one control transceiver.
The SN75971B is available in a B2 (20 Mxfer)
version and a B1 (10 Mxfer) version.
In a typical differential SCSI node, the SCSI controller
provides an enable for each external RS-485
transceiver channel. This could require as many as 27
extra terminals for a 16-bit differential bus controller or relegate a 16-bit, single-ended controller to only an 8-bit
differential bus. Using the standard nine SCSIcontrol signals, the SN75970B control transceiver decodes the
state of the bus and enables the SN75971B data transceiver to transmit the single-ended SCSI input signals
(A side) differentially to the cable or receive the differential cable signals (B side) and drive the single-ended
outputs to the controller.
A reset function, which disables all outputs and clears internal latches, can be accomplished from two external
inputs and two internally-generated signals. RESET (reset) and DSENS (differential sense) are available to
external circuits for a bus reset or to disable all outputs should a single-ended cable be inadvertently connected
to a differential connector. Internally-generated power-up and thermal-shutdown signals have the same affect
when the supply voltage is below approximately 3.5 V or the junction temperature exceeds 175°C.
