In a system clocked at 20 MHz (50 ns period), that leaves 20 ns for setup and hold — workable for most microprocessor buses but tight if the latch sits in a feedback or read-modify-write loop. The 7.8 mA output drive is enough for a lightly loaded bus (2–3 TTL loads or a handful of CMOS inputs), but if you are fanning out to more than five loads, budget for a buffer stage or use a 74HCT variant with higher drive. ## Tri-state outputs and the 8:8 circuit The tri-state output enable (OE) lets you share the bus with other drivers — common in memory address latching, I/O port expansion, or bidirectional data paths. The 8:8 circuit means eight inputs map to eight outputs with a single latch-enable (LE) and output-enable (OE) controlling all channels. One independent circuit per package, so you get one 8-bit latch in the 20-SOIC.","metaTitle":"CD74HC373M 74HC Octal D-Type Transparent Latch, 30ns","metaDescription":"CD74HC373M octal D-type transparent latch with tri-state outputs. 2V-6V supply, 30ns propagation delay, 7.8mA drive, -55°C to 125°C.
