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 ofbeing 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 thatwhile 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.
