About this manual

This document provides a datasheet for the 54173/DM54173/DM74173 TRI-STATE Quad D Registers. These four-bit registers contain D-type flip-flops with totem-pole TRI-STATE outputs, capable of driving highly capacitive or low-impedance loads. The high-impedance state and increased high-logic-level drive provide these flip-flops with the capability of driving the bus lines in a bus-organized system without need for interface or pull-up components. Gated enable inputs are provided for controlling the entry of data into the flip-flops.
