... WITH 3-STATE OUTPUTS; OCTAL D-TYPE FLIP-FLOP WITH 3-STATE OUTPUT The SN54 / 74LS373 consists of eight latches with 3-state outputs for bus organized system applications. The flip-flops appear transparent to the data (data changes asynchronously) when Latch Enable (LE) is HIGH. When LE is LOW, the data that meets the setup times is latched. Data appears on the bus when the Output Enable (OE) is LOW ...
