The 15ns propagation delay is a typical figure at 5V supply; it sets the timing budget for address/data setup and hold on the receiving side. At 33 MHz bus speeds, this leaves roughly 15ns of margin before the next clock edge — adequate for most 8-bit microcontroller and legacy peripheral interfaces, but tight for faster 16-bit or 32-bit buses. The 7.8mA source and sink capability is symmetric, which simplifies drive calculations for bus lines, LED indicators, or low-power relay coils. For higher fan-out or longer PCB traces, consider a bus transceiver with stronger drive or add line buffers. ## Package and temperature — design-in checklist Supply decoupling with a ceramic capacitor close to the VCC pin is recommended for clean latch operation at 15ns edge rates. ## Lifecycle and compliance For designs requiring a through-hole equivalent, the SN74HC373N is the same die in a different package — verify fit before substituting.","metaTitle":"SN74HC373NS 74HC D-Type Transparent Latch, 15ns, 20-SOIC","metaDescription":"SN74HC373NS — 74HC D-Type Transparent Latch with Tri-State outputs, 2V–6V supply, 15ns propagation delay, −40°C to 85°C.

When the latch-enable (LE) input is high, the outputs follow the data inputs (transparent mode). When LE goes low, the last data state is latched and held.
