Technical content
The LSTTL/MSI SN54L/74LS158 is a high speed Quad 2-input Multiplex- er. It selects four bits of data from two sources using the common Select and Enable inputs. The four buffered outputs present the selected data in the inverted form. The LS158 can also generate any four of the 16 different functions of two variables. The LS158 is fabricated with the Schottky barrier diode process for high speed and is completely compatible with all Motorola TTL families.

The LS158 is a Quad 2-input Multiplexer fabricated with the Schottky barrier diode process for high speed. It selects four bits of data from two sources under the control of a common Select Input (S) and presents the data in inverted form at the four outputs. The Enable Input (E) is active LOW. When E is HIGH, all of the outputs (Z) are forced HIGH regardless of all other inputs. The LS158 is the logic implementation of a 4-pole, 2-position switch where the position of the switch is deter- mined by the logic levels supplied to the Select Input. A common use of the LS158 is the moving of data from two groups of registers to four common output busses. The particular register from which the data comes is determined by the state of the Select Input. A less obvious use is as a function generator. The LS158 can generate four functions of two variables with one variable common. This is useful for implementing gating functions.
