- Package Includes: 1 X 74LS253 IC - (SMD Package) 3-State Dual 4-Input Multiplexer IC (74253 IC)
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.
