MC74LCX158DG

The MC74LCX158DG from On Semiconductor is a low-voltage CMOS quad 2-input multiplexer designed for high performance. It operates within a supply voltage range of 2.3V to 3.6V, making it suitable for modern low-voltage systems. A key feature is its 5V tolerant inputs, which allow for seamless interface capability with 5V TTL logic, reducing design complexity when integrating with older systems.

This device functions as a quad 2-input multiplexer, enabling the selection of four bits of data from two sources using select and enable inputs. The outputs present the selected data in an inverted form. The MC74LCX158DG offers LVTTL and LVCMOS compatibility, along with a balanced output sink and source capability of 24 mA. Its near-zero static supply current contributes to reduced system power requirements.

Packaged in a 16-SOIC surface-mount package, the MC74LCX158DG is designed for operation across a wide temperature range of -40°C to 85°C. Its high impedance TTL compatible inputs minimize current loading on input drivers, while TTL compatible outputs enhance switching noise performance. The device also exhibits robust ESD protection, exceeding 2000V for the Human Body Model and 200V for the Machine Model, and has a latchup performance exceeding 500 mA.
