What are the key features of SN74LVTH16646DLG4?
- 16-bit bidirectional registered transceiver enables simultaneous data flow in both directions on wide parallel buses with a single device
- LVTTL 3.3 V logic family with 5 V tolerant inputs allows direct connection between legacy 5 V and modern 3.3 V system buses
- 64 mA output sink current per channel supports high-capacitance PCB traces up to 50 pF, reducing the need for external bus buffers
- 56-pin SSOP (DL) package provides high pin density for 16-bit bus interfaces in compact industrial and networking board designs
What is SN74LVTH16646DLG4 used for?
The SN74LVTH16646DLG4 is commonly used in CPU-to-memory interface bus buffering in embedded systems and industrial controllers where 16-bit data buses must bridge 3.3 V logic on a host processor and 5 V peripheral logic. It also suits backplane bus drivers in PLC racks and FPGA I/O expansion boards, where registered outputs latch data synchronously to reduce bus noise and timing hazards. Its high-drive capability makes it a reliable choice for buffering address and data lines on multi-board VME or compact PCI systems.
