Product Summary
The 54LS253 is a TRI-STATE multiplexer. It 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.
Parametrics
54LS253 absolute maximum ratings: (1)supply voltage: 7V; (2)input voltage: 7V; (3)operating free air temperature range: -55 to 125℃; (4)storage temperature range: -65 to 150℃.
Features
54LS253 features: (1)TRI-STATE version of LS153 with same pinout; (2)Schottky-diode-clamped transistors; (3)Permit multiplexing from N-lines to one line; (4)Performs parallel-to-serial conversion; (5)Strobe/output control; (6)High fanout totem-pole outputs; (7)Typical propagation delay.
