These devices are pin-to-pin compatible Sipex's SP and SP devices as well as popular industry standards. The SP and SP feature Sipex's BiCMOS process allowing low power operation out sacrificing performance. The SP and SP meet the electrical specifications of RS- and RS- serial protocols up to 0Mbps under load. The SP features a common driver enable control. The SP provides independent driver enable controls for each pair of drivers. Both devices feature tri-state outputs and a -V to +V common-mode input voltage range.

5 FEATURES The SP and the SP are +.V low power quad line drivers that meet the specifications of the RS- and RS- serial protocols. These devices are pin-to-pin compatible Sipex's SP and SP devices as well as popular industry standards. The SP and SP devices feature Sipex's BiCMOS process allowing low power operation out sacrificing performance. The RS- standard is ideal for multi-drop applications or for long distance interfaces. RS- allows up to drivers and receivers to be connected to a data bus, making it an ideal choice for multi-drop applications. Since the cabling can be as long as,000 feet, RS- transceivers are equipped a wide (-V to +V) common mode range to accomodate ground potential differences. ata is virtually immune to noise in the transmission line because the RS- protocol is a differential interface. river The drivers for both the SP and SP have differential outputs. The typical voltage output swing no load will be 0V to +V. With worst case loading of Ω across the differential outputs, the driver can maintain greater than +.V voltage levels. The drivers of the SP feature active HIGH and active LOW common driver enable controls. Refer to SP Truth Table in Table. The SP provides independent, active high driver enable controls for each pair of drivers. Refer to SP Truth Table in Table. The driver outputs are short-circuit limited to 0mA. The SP and SP drivers meet the electrical specifications of RS- and RS- serial protocols up to 0Mbps under load. AC PARAMETERS = +.V±%; typicals at C; T AMB = C unless otherwise noted. PARAMETER MIN.
