1.65V to 3.6V supply — what it buys the board
The Texas Instruments SN74LVCH16240ADGG is a 4-element inverting buffer with 3-state outputs from the 74LVCH family, packaged in a 48-TFSOP (6.10mm width) and also offered in a 48-TSSOP footprint. Its supply range of 1.65V to 3.6V lets it bridge 1.8V-core logic to a 3.3V peripheral bus without a level translator, or run directly from a 3.3V or 2.5V rail. Each of the four elements handles 4 bits, giving you 16 bits of buffered, inverting bus interface in a single package.
24 mA symmetric drive — fan-out and signal integrity
The 24mA output drive at both high and low states is the headline number for bus loading. At 3.3V supply, that drive strength can handle a heavily loaded backplane or memory-array address bus with reasonable edge rates. The symmetric drive means the rising and falling transition times match closely, which simplifies timing closure on a bidirectional bus where the round-trip delay budget is tight. For a 16-bit wide memory or peripheral bus running at 50-100 MHz, this buffer keeps the signal edges clean without excessive overshoot.
Industrial temperature grade — deployment context
The 74LVCH family's CMOS process holds leakage low across the temperature range, so the quiescent supply current doesn't climb sharply at 85°C the way a bipolar bus driver would. If your board sees condensation cycles or unheated storage, the industrial range covers it without derating.
Package and footprint note
Surface-mount in a 48-TFSOP (0.240", 6.10mm width) and also listed with a 48-TSSOP supplier device package. The two are footprint-compatible for layout — TFSOP is the thin version of TSSOP with the same body dimensions and pin pitch. Standard MSL 3 handling applies: bake before reflow if the moisture barrier bag has been open beyond the floor-life window. The 0.5mm lead pitch needs a fine-pitch soldering tip or stencil; no thermal pad to worry about.
