The output stage can source or sink 6 mA per channel, sufficient to drive a single LSTTL load or a short PCB trace directly.","metaTitle":"74HCT573D/C4118 D-Type Transparent Latch – NXP 74HCT","metaDescription":"NXP 74HCT573D/C4118 D-Type Transparent Latch, 8-bit, tri-state outputs, 17ns propagation delay, 4.5V–5.5V supply, -40°C to 125°C, SOIC-20.
