Top Features:
- Schottky-diode-clamped transistors
- Multiplexing from N-lines to one line
- Parallel-to-serial conversion
- Strobe/output control
Each of these Schottky-clamped data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the AND-OR gates. Separate output control inputs are provided for each of the two four-line sections. The 3-STATE outputs can interface directly with data lines of bus-organized systems. With all but one of the common outputs disabled (at a high impedance state), the low impedance of the single enabled output will drive the bus line to a HIGH or LOW logic level.
High fanout totem-pole outputs ensure efficient performance, with a typical power dissipation of 35mW.
