Dual 4-line to 1-line multiplexer
Product specification
74F153
FEATURES
• Non-inverting outputs
• Separate enable for each section
• Common select inputs
• See 74F253 for 3-State version
DESCRIPTION
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.
