HEF4049BP Description

Short technical summary and product information.

The HEF4049BP is a hex inverting buffer IC from NXP Semiconductors, providing six inverting buffers with high current output capability. This makes it suitable for driving TTL logic or high capacitive loads.

 

Key electrical specifications include a guaranteed fan-out of up to 2 standard TTL loads, 9 for 74LS, and 16 for 74L. Propagation delays are typically 35ns at 5V and 15ns at 10V. The device can also be used for high-to-low level logic conversion, accepting input voltages up to 15V.

 

Packaged in a 16-lead DIL package, the HEF4049BP is designed for through-hole mounting. Its input protection circuit allows input voltages to exceed the supply voltage, enhancing its versatility in mixed-voltage systems.

 

Applications include LOCMOS to DTL/TTL conversion and driving multiple TTL loads due to its high sink current capability.
