DM54173 - Quad D Registers

Description

These four-bit registers contain D-type flip-flops with totempole 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 syste

54173 DM54173 DM74173 TRI-STATE Quad D Registers June 1989 54173 DM54173 DM74173 TRI-STATE Quad D Registers General Description These four-bit registers contain D-type flip-flops with totempole 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 When both data-enable inputs are low data at the D inputs are loaded into their respective flipflops on the next positive transition of the buffered clock input Gate output control inputs are also provided When both are low the nor
