description

The SN75976A is an improved replacement for  
the industry’s first 9-channel RS-485  
7DE/RE  
8A  
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

Terminals 13 through 17 and 40 through 44 are  
connected together to the package lead frame  
and signal ground.  
transferspersecond. Theskewlimitensuresthatthepropagationdelaytimes, notonlyfromchannel-to-channel  
but from device-to-device, are closely matched for the tight skew budgets associated with high-speed parallel  
data buses.  
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.
