The 74HC158 is a high-speed Si-gate CMOS device that is pin-compatible with low-power Schottky TTL (LSTTL). Compliant with JEDEC standard no. 7A, this quad 2-input multiplexer is designed to select 4 bits of data from two sources, controlled by a common data select input (S). The selected data is presented on the four outputs in an inverted form, with an active LOW enable input (E).

Key Features:

  • Quad 2-Input Multiplexer: Selects data from two sources and presents it in an inverted form on four outputs.
  • Common Data Select Input (S): Determines which data source is selected.
  • Active LOW Enable Input (E): When E is HIGH, all outputs (1Y to 4Y) are forced HIGH regardless of other input conditions.
  • Versatile Applications: Ideal for moving data from two groups of registers to four common output buses, and for use as a function generator. It can implement any four of the 16 different functions of two variables with one variable common.

Logic Implementation:

  • The 74HC158 functions as a 4-pole, 2-position switch, with the switch position determined by the logic levels applied to S.
  • The logic equations for the outputs are:
    • 1Y = E·(1I1·S + 1I0·S)
    • 2Y = E·(2I1·S + 2I0·S)
    • 3Y = E·(3I1·S + 3I0·S)
    • 4Y = E·(4I1·S + 4I0·S)

Comparison:

  • The 74HC158 is identical to the 74HC157, except it has inverting outputs.

Benefits:

  • High-Speed Performance: Ensures quick and efficient data processing.
  • Low-Power Consumption: Suitable for power-sensitive applications.
  • Flexible Data Handling: Easily moves data between registers and common output buses.

Applications:

  • Data multiplexing in digital systems.
  • Function generation and implementation of complex logic functions.
  • Bus-oriented systems for data routing.
