CD4049UBD Description

Short technical summary and product information.

The CD4049UBD from Texas Instruments is a versatile 6-channel inverting hex buffer. It is designed to function as a CMOS to DTL or TTL converter, capable of driving up to two DTL or TTL loads directly. This device operates over a wide voltage range of 3V to 18V, making it suitable for various applications.

 

The CD4049UBD features a single input per gate and provides an inverted output. Its input logic levels can exceed the VCC supply voltage, which is beneficial for logic-level conversions. The device is specified for an operating temperature range of -55°C to 125°C.

 

Packaged in a 16-SOIC (Surface Mount) configuration, the CD4049UBD is designed for easy integration into printed circuit boards. Its high sink current capability and wide operating voltage make it a reliable choice for signal buffering and level shifting tasks in digital circuits.
