Texas Instruments SN74LVT8996 3.3-V ABT 10-Bit Addressable Scan Ports Multidrop-Addressable IEEE STD 1149.1 (JTAG) TAP Transceiver SN74LVT8996PWR

The SN74LVT8996PWR is a 3.3-V 10-bit addressable scan port multidrop-addressable IEEE STD 1149.1 (JTAG) TAP transceiver from Texas Instruments. It is designed to facilitate testing of complex circuit assemblies by extending scan access beyond the board level. This device supports both 3.3-V and 5-V interfacing, making it versatile for various applications. The transceiver features a switch-based architecture that allows direct connection of primary TAP signals to secondary TAP signals, minimizing the need for additional wiring. It supports a simple addressing protocol, enabling up to 1021 user-specified board addresses. The device also includes a bypass function for direct connections without using shadow protocols, which is beneficial in board-test environments. The SN74LVT8996PWR is characterized for operation from -40°C to 85°C and offers high-drive outputs, ensuring compatibility with backplane interfaces. It provides robust ESD protection and latch-up performance, making it suitable for demanding applications. The device is available in a TSSOP package, which is compact and suitable for space-constrained designs.
