National Semiconductor TNT4882

The TNT4882 provides a single-chip IEEE 488.2 Talker/Listener interface to the general-purpose interface bus (GPIB). The TNT4882 combines the circuitry of the NAT4882 IEEE 488.2 application-specific integrated circuit (ASIC), Turbo488 performance-enhancing ASIC, and GPIB transceivers to create a single-chip IEEE 488.2 interface. The TNT4882 is ideal for use in all IEEE 488 instrument designs because of its small size, surface-mount ability, and performance enhancements that include HS488, a new high-speed mode for GPIB transfers.
