74LS253 IC - (SMD Package) 3-State Dual 4-Input Multiplexer IC (74253 IC)

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. Features :- 3-STATE version of 74LS153 with same pinout Schottky-diode-clamped transistors Permit multiplexing from N-lines to one line Performs parallel-to-serial conversion Strobe/output control High fanout totem-pole outputs Typical power dissipation 35mW Specifications :- Supply Voltage : 4.75 - 5.25V Input HIGH Voltage : 2.0V Input LOW Voltage : 0.8V HIGH Level Output Current : -2.6mA LOW Level Output Current : 24 Free Air Operating Temperature : 70°C Package Includes :- 1 X 74LS253 IC - (SMD Package) 3-State Dual 4-Input Multiplexer IC (74253 IC)
