The 74F253 is a dual 4-input multiplexer with 3-STATE outputs. It can select two bits of data from four sources using common select inputs. The output may be individually switched to a high impedance state with a HIGH on the respective Output Enable (OE) inputs, allowing the outputs to interface directly with bus oriented systems.
This document is a technical datasheet for the Fairchild Semiconductor 74F253, a dual 4-input multiplexer featuring non-inverting 3-STATE outputs. The device allows selection of two bits from four sources using common select inputs and can switch outputs to a high impedance state via individual Output Enable (OE) inputs.
The individual Output Enable (OE) inputs force the outputs to a high impedance state when HIGH.
The absolute maximum input voltage applied to any pin relative to ground is +7.0V.
The current applied to a standard output in the HIGH state ranges from -3 mA to 24 mA.
The device has a minimum ESD latch-up passing voltage of 4000V.
