Each output can sink or source 24 mA, enough to drive a lightly loaded bus or a handful of CMOS inputs without an extra line driver. The 3-state outputs let you share a data bus across multiple peripherals by pulling the output-enable pins high. ## Supply range — why 1.65V to 3.6V matters The 1.65V to 3.6V supply window covers the three most common low-voltage logic rails: 1.8V, 2.5V, and 3.3V. If your design has a 2.5V FPGA bank talking to a 3.3V peripheral, this buffer sits between them without a level translator — the input thresholds track the supply. At 1.8V the 24 mA drive drops, but the part still switches cleanly. For a board that ships with both 1.8V and 3.3V variants, one BOM line covers both. ## Output drive and bus loading Rated for 24 mA high and low at 3.3V, the outputs can drive a 50 pF load at the rated speed without visible edge degradation. That 24 mA figure is the DC limit — for short bus stubs or point-to-point signals it leaves margin. If you are fanning out to more than four or five CMOS loads, add a series resistor to damp reflections; the 3-state control makes it easy to disconnect the bus when the buffer is not selected. ## Temperature grade and environment If your application lives in a heated indoor rack, the commercial 0°C to 70°C range is a subset anyway. ## Lifecycle and sourcing posture For production builds, the 20-TSSOP package is widely second-sourced across the 74LVCH family — if you need a dual-sourcing hedge, the same function in a different package (e.g., 20-SOIC) is a straightforward board spin.","metaTitle":"SN74LVCH244APWT Buffer, Non-Inverting, 1.65V–3.6V, 24mA","metaDescription":"Texas Instruments SN74LVCH244APWT octal buffer with 3-state outputs, 1.65V–3.6V supply, 24mA drive, -40°C to 85°C.
