With a 2.2 ns typical propagation delay and 24 mA symmetrical output drive (high and low), this latch keeps up with fast memory and processor buses without adding a timing margin penalty. ## Package and board-level integration Supplied in a 56-TFSOP (0.240\", 6.10 mm width) package, also designated as 56-TSSOP by NXP — the 0.50 mm pitch footprint demands careful PCB layout for fan-out and decoupling placement.","metaTitle":"74ALVCH16843DGGY NXP 18-bit transparent latch, 2.3-3.6V","metaDescription":"NXP 74ALVCH16843DGGY 18-bit D-type transparent latch, 2.2ns propagation delay, 24mA output drive, 56-TSSOP.
