Product Overview
The SN74LVCH16952ADL is a 16-bit registered bus transceiver from Texas Instruments, designed for 3.3-V VCC operation with 5-V tolerant I/Os. It provides bidirectional communication between two data buses (A and B) with direction control (DIR) and output enable (OE) inputs. The device features dual 8-bit registers for each bus, allowing data flow in both directions. It is housed in a 56-pin SSOP package, ideal for space-constrained applications.
