That is 36 switch elements in a single 56-pin TFSOP package, controlled by a common select bus. Supply range is 4.5V to 5.5V from a single rail, making it a direct drop-in for 5V TTL/CMOS logic environments. ## Output drive and signal integrity High and low output current ratings are 15 mA (source) and 64 mA (sink) — the sink capability is more than four times the source, which matters when the switch is driving a bus with asymmetric loading like a fan-out buffer or a memory address line. The 64 mA sink allows the switch to hold a logic low against a strong pull-up without the output creeping above VIL. Because the part is a pass-gate mux (no latching or registered outputs), propagation delay is negligible — the switch is essentially a set of NMOS/CMOS transmission gates. The buyer should confirm that the channel resistance (not listed here) stays low enough for the edge rates in their specific bus; typical 74CBT Ron is in the 5–10 Ω range. ## Active production — no obsolescence risk Lifecycle status is Active, so this is not a NRND or EOL part. No last-time-buy window to chase. ROHS3 compliant — no exemption-based restrictions for EU or California markets. The 56-TFSOP package is lead-free compatible with standard reflow profiles. ## Package and PCB integration Housed in a 56-TFSOP (0.240\", 6.10 mm width) — a fine-pitch TSSOP derivative. The 0.50 mm ball pitch demands careful PCB fan-out: a 4-layer board with microvias or blind vias is typical for routing all 56 signals out from under the package body. The supplier device package is listed as 56-TSSOP, confirming the footprint matches standard TSSOP-56 land patterns. Surface-mount only; no through-hole variant exists. The tape-and-reel option is the standard delivery format for pick-and-place assembly; cut tape is also available for prototyping or low-volume builds.","metaTitle":"SN74CBT16214DGGR Mux/Demux 12x1:3 56-TSSOP - TI 74CBT","metaDescription":"Texas Instruments SN74CBT16214DGGR 12 x 1:3 multiplexer/demultiplexer, 4.5V-5.5V supply, -40°C to 85°C, 56-TFSOP.
