MC14049U Description

Short technical summary and product information.

The MC14049U from On Semiconductor is a hex inverter/buffer IC built with complementary MOS technology. It is suitable for applications requiring low power consumption and high noise immunity. This device can perform logic-level conversion using a single supply voltage, VDD, and its input signal high level (VIH) can exceed the VDD supply voltage.

Key electrical specifications include a wide supply voltage range from 3.0 V to 18.0 V. The input voltage range is -0.5 V to 18.0 V, and the output voltage range is -0.5 V to VDD + 0.5 V. It can handle an input current of ±10 mA per pin and an output current of +45 mA per pin. The device operates across an ambient temperature range of -55 °C to 125 °C.

The MC14049U is available in multiple package types, including PDIP-16, SOIC-16, SOEIAJ-16, and TSSOP-16. Standard package quantities vary by type, with options such as 2000 for PDIP-16, 2400 for SOIC-16, and 2500 for SOIC-16 Tape & Reel. Unused inputs should be tied to an appropriate logic voltage level (VSS or VDD), and unused outputs should be left open.
