PHILIPS 74F153 handbook

The 74F153 is a dual 4-input multiplexer that can select 2 bits of data from up to four sources selected by common Select inputs (S0, S1). The two 4-input multiplexer circuits have individual active-Low Enables (Ea, Eb) which can be used to strobe the outputs independently. Outputs (Ya, Yb) are forced Low when the corresponding Enables (Ea, Eb) are High. The 74F153 is the logic implementation of a 2-pole, 4-position switch where the switch is determined by the logic levels supplied to the common select inputs.
