When the enable control line is at logic level “0”, the buffer output is disabled and a high impedance condition, Hi-Z is present on the output.
WebHi, I was reading about Tri-State Buffers, and found out that the following is a very typical approach to use a Tri-state buffer: entity GLCD_BI_DIRECTIONAL_PORT is Port ( GLCD_DATA_WRITE : in STD_LOGIC_VECTOR (3 downto 0); GLCD_DATA_READ : out STD_LOGIC_VECTOR (3 downto 0); CONTROL : in STD_LOGIC; GLCD_PINS : inout … WebTI’s SN74LS244 is a 8-ch, 4.75-V to 5.25-V bipolar buffers with 3-state outputs.

WebIf you want more than one functional unit output to share a bus, and especially when you are wiring up an external system using MSI/SSI logic parts, then tri-stating makes sense. You can add additional functional units to the bus without going nuts.
WebCAUSE: The design contains one or more always-enabled tri-state buffers that feed a non-tri-state logic, an open-drain buffer, or an output pin. The Quartus Prime software removes the tri-state buffer(s) because they are equivalent to a wire.
