HD74LS373
Octal D-type Transparent Latches (with three-state outputs)
The HD74LS373, 8-bit register features totem-pole three-state outputs designed specifically for driving highly-
capacitive or relatively low-impedance loads. The high-impedance third state and increased high-logic-level drive
provide this register with the capacity of being connected directly to and driving the bus lines in a bus-organized system
without need for interface or pull-up components. They are particularly attractive for implementing buffer registers, I/O
ports, bidirectional bus drivers, and working registers.
The eight latches are transparent D-type latches meaning that while the enable (G) is high the Q outputs will follow the
data (D) inputs. When the enable is taken low the output will be latched at the level of the data that was setup.
