description
The SN75976A is an improved replacement for
the
industry’s
first
transceiver — the SN75LBC976. The A version
offers improved switching performance, a smaller
package, and higher ESD protection. The
SN75976A is offered in two versions. The ’976A2
skew limits of 4 ns for the differential drivers and
5 ns for the differential receivers complies with the
recommended skew budget of the Fast-20 SCSI
standard for data transfer rates up to 20 million
transfers per second. The ’976A1 supports the
Fast SCSI skew budget for 10 million
transfers per second. The skew limit ensures that the propagation delay times, not only from channel-to-channel
but from device-to-device, are closely matched for the tight skew budgets associated with high-speed parallel
data buses.
9-channel
RS-485
The patented thermal enhancements made to the 56-pin shrink small-outline package (SSOP) of the SN75976
have been applied to the new, thin shrink, small-outline package (TSSOP). The TSSOP package offers even
less board area requirements than the SSOP while reducing the package height to 1 mm. This provides more
board area and allows component mounting to both sides of the printed circuit boards for low-profile,
space-restricted applications such as small form-factor hard disk drives.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
Terminals 13 through 17 and 40 through 44 are
connected together to the package lead frame
and signal ground.
