    3-STATE Dual 1-of-4 Line Data Selector/Multiplexer

    General Description This Data Selector/Multiplexer contains full on-chip decoding to select one-of-four data sources as a result of a unique two-bit binary code at the Select Inputs. Each of the two Data Selector/Multiplexer circuits have their own separate Data and Output Control inputs and a no

    3-STATE Quad 1-of-2-Line Data Selector/Multiplexer

    General Description These data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four 3-STATE outputs that can interface directly with data lines of bus-organized systems. A 4-bit word selected from one of two sources is routed to the four outputs.

    Octal D-Type Edge-Triggered Flip-Flop with Clear

    General Description These monolithic, positive-edge-triggered flip-flops utilize TTL circuitry to implement D-type flip-flop logic with a direct clear input. Information at the D inputs meeting the setup requirements is transferred to the Q outputs on the positive-going edge of the clock pulse.
