6A 21 36 4B+
The SN75976A is an improved replacement for the industry’s first 9-channel RS-485 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

Terminals 13 through 17 and 40 through 44 are connected together to the package lead frame and signal ground.
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.
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 ponent mounting to both sides of the printed circuit boards for low-profile, space-restricted applications such as small form-factor hard disk drives.
