74F157A; 74F158A Data Selectors/multiplexers

The 74F157A is a high speed Quad 2-Input Multiplexer which selects 4 bits of data from one of two sources under the control of a common Select input (S). The Enable input (E) is active when Low. When E is High, all of the outputs (Yn) are forced Low regardless of all other input conditions. Moving data from two Registers to a common output bus is a common use of the 74F157A. The state of the Select input determines the particular Register from which the data comes. The device is the Logic implementation of a 4-pole, 2-position Switch where the position of the Switch is determined by the Logic levels supplied to the Select input. The 74F158A is similar, but has inverting outputs (Yn).
