CD4049UBF Description

Short technical summary and product information.

The CD4049UBF from Texas Instruments is a military-grade, 6-channel inverting buffer and converter. It features logic-level conversion capabilities using a single supply voltage (VCC), allowing the input signal high level (VIH) to exceed VCC when used for level shifting.

 

This device is suitable for converting CMOS to DTL or TTL logic levels and can directly drive two DTL or TTL loads. It operates over a wide voltage range of 3V to 18V. Key electrical characteristics include a maximum propagation delay of 90ns at 15V with a 50pF load. The operating temperature range is -55°C to 125°C.

 

The CD4049UBF is packaged in a 16-pin CDIP (Ceramic Dual In-line Package) and is designed for through-hole mounting. It offers high sink current for driving TTL loads and is 100% tested for quiescent current at 20V. The maximum input current is limited to 1µA at 18V over the full package temperature range.

 

This component is intended for applications requiring robust logic-level translation and buffering in demanding environments.
