Its 3V to 18V supply range lets it run on the same rail as the rest of a 4000B logic family without a separate regulator — useful for battery-operated or mixed-voltage backplanes where a 5V or 12V bus is already present. At 125°C the CMOS leakage current rises, but the 4000B process holds static power well below bipolar logic. ## Output drive and propagation delay — bus timing and fan-out Each latch delivers 6.8mA source and sink — enough to drive one standard 4000B gate input or a low-power LED directly. The 50ns propagation delay sets the maximum cascaded clock rate around 10 MHz; above that the bus turnaround time eats into the setup margin. The tri-state output allows multiple CD4043BPWR devices to share a common data bus without contention — the enable signal disconnects the latch from the line, which is the standard method for multiplexed register banks. ## Package, lifecycle, and sourcing posture The CD4043BPWR is in a 16-TSSOP package. The supplier device package is 16-TSSOP.","metaTitle":"CD4043BPWR Quad NOR S-R Latch, Tri-State, 3V-18V","metaDescription":"Texas Instruments CD4043BPWR quad NOR R/S latch with tri-state outputs.
