N74F257AN Datasheet

Quad 2-line to 1-line selector/multiplexer, non-inverting (3-State)


The 74F257A has four identical 2-input multiplexers with 3-State outputs which select 4 bits of data from two sources uncer control of a common Select (S) input. The I0a inputs are selected when the  common Select input is Low and the I1n inputs are selected when the common Select input is High. Data appears at the outputs in true non-inverted form from the selected inputs. The 74F257A 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 common Slect input.

• Industrial range available (–40°C to +85°C)
• Multifunction capability
• Non-inverting data path
• 3-State outputs
• See 74F258A for inverting version
