Texas Instruments 74ACT11139
The 74ACT11139 is designed for use in high-performance memory-decoding or data-routing applications that require very short propagation delay times. The 74ACT11139 is composed of two individual 2-line to 4-line decoders in a single package. The active-low enables (1G or 2G) can be used as data lines in demultiplexing applications.| Part No. | 74ACT11139 |
