74AC253SJ

Signal Switches, Multiplexers, Decoders Overview

The Fairchild Semiconductor 74AC253SJ is a dual 4-input multiplexer with 3-STATE outputs. It selects two bits of data from four sources using common select inputs. The device features non-inverting outputs that can be individually switched to a high impedance state via Output Enable (OE) inputs, facilitating direct interface with bus-oriented systems. Packaged in a 16-Lead Small Outline Package (SOP), it operates within a voltage range of 2V to 6V and supports an operating temperature range of -40°C to +85°C.
