This data sheet introduces the features and characteristics of CD54HC540F3A. The product is an eight-channel buffer and line driver with three-state outputs and the ability to drive 15 LSTTL loads.
The document provides detailed information on the CD54/74HC540, CD74HCT540, CD54/74HC541, and CD74HCT541 octal buffer and line‑driver ICs. It includes features, functional diagrams, pinouts, ordering information, absolute maximum ratings, DC electrical specifications, and switching performance data.
Key sections cover propagation delay, input and output voltage levels, temperature operating range, package options (CERDIP, PDIP, SOIC), and test circuit waveforms. An important notice at the end outlines TI's warranty and liability terms.
| Typical Propagation Delay | 9 ns |
