onsemi 20-SOIC 74F373SC

The 74F373SC is a high-speed CMOS-based octal D-type transparent latch with three-state outputs. When the latch enable (LE) input is high, data from inputs D0 to D7 pass through to the corresponding outputs Q0 to Q7. When LE is low, the data on the D pins is latched and held at the output. The device's outputs are designed for bus-oriented systems as they can be set to a high-impedance state, allowing multiple devices to share a common bus without conflict. It offers improved noise immunity compared to its TTL counterparts due to its advanced CMOS technology.
