What this 16-bit buffer does in your design
The Texas Instruments SN74LVCH162244ADL is a 16-bit non-inverting buffer with 3-state outputs, organized as four independent 4-bit elements. It belongs to the 74LVCH family — low-voltage CMOS with bus-hold circuitry that eliminates the need for external pull-up resistors on unused inputs. The part operates from a 1.65V to 3.6V supply, making it a direct fit for 3.3V and 1.8V logic systems without any level-shifting interface. Each output can source or sink 12 mA, enough to drive a handful of CMOS loads or a short PCB trace, but not intended for heavy backplane or cable driving. The 48-pin SSOP package (0.295" body width) is a common footprint for 16-bit bus-interface logic, and the -40°C to 125°C operating temperature range qualifies it for industrial and automotive under-hood environments.
Supply voltage and 3.3V system fit
The 1.65V to 3.6V supply range covers both 1.8V and 3.3V rails. At 3.3V the device runs within its rated window, so no level shifting is needed when interfacing with a 3.3V microcontroller, FPGA, or memory controller. The bus-hold feature keeps the last valid logic level on an undriven input, which prevents floating inputs and reduces system noise — a practical advantage in mixed-voltage boards where signal integrity matters.
Temperature grade and deployment context
Rated for -40°C to 125°C ambient, this buffer is specified for the full industrial and automotive temperature envelope. It can sit in an engine-control module, a factory-automation PLC, or an outdoor telecom cabinet without derating concerns. The 125°C upper limit also covers the junction temperature rise from self-heating in a densely populated board.
Lifecycle and sourcing posture
The SN74LVCH162244ADL is listed as Active with ROHS3 compliance. For a production BOM, this part carries no imminent obsolescence risk.
