description
The 74ACT1 1139 is designed for use in high-performance memory-decoding or data-routing applications that require very short propagation delay times. In high-performance memory systems, this decoder is used to minimize the effects of system decoding.
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. This decoder/demultiplexer
features fully buffered inputs, each of which represents only one normalized load to its driving circuit. The 74ACT11139 is characterized for operation from –40°C to 85°C.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
2. The maximum package power dissipation is calculated using a junction temperature of 150_C and a board trace length of 750 mils, except for the N package, which has a trace length of zero.

Not more than one output should be tested at a time, and the duration of the test should not exceed 10 ms.
This is the increase in supply current for each input that is at one of the specified TTL voltage levels rather than 0 V or VCC.
