Bus buffer with 3-state control for 3.3V logic systems
The Texas Instruments CY74FCT163827CPAC is a 20-bit non-inverting buffer organized as two 10-bit elements, each with independent 3-state output enables. It's the part you reach for when a bus needs clean drive without inversion — address lines, control signals, or data paths running on a 3.3V rail. The 24 mA source and sink capability per pin handles moderate fan-out and keeps signal edges crisp on point-to-point or short backplane traces.
Supply rail and temperature fit
Rated for 2.7V to 3.6V, this buffer sits naturally on a 3.3V supply with margin for droop.
Package and footprint reality
Housed in a 56-TFSOP (6.10 mm width) package, also known as 56-TSSOP. The 0.65 mm pitch is standard for this body size; a fine-pitch soldering profile and stencil are assumed. The Bulk shipping form means the parts come in tubes or trays — not cut tape — so factor that into your pick-and-place feeder setup.
Lifecycle and production status
For new designs it's a safe choice, but if your BOM requires RoHS compliance, this specific variant won't pass — check the lead-free suffix options in the FCT family.
