The F can be used as an 8-output demulti. Physical Dimensions inches millimeters unless otherwise noted.
The F can be used as an 8-output demultiplexer by using one of the active LOW Enable inputs as the data input and the other Enable inputs as strobes. Recognized as a LOW Signal. Functional operation under these conditions is not implied. This multiple enable function allows easy parallel expansion of the device to a 1-of 5 74v138 to 32 lines decoder with just four F devices and one inverter See Figure 1.
Absolute maximum ratings are values beyond which the device may be damaged or have its useful life impaired. Absolute maximum ratings are values beyond which the device. The F features three Enable. Current Applied to Output. Input Clamp Diode Voltage.
Ambient Temperature under Bias. LOW outputs O 0? Specify by appending the suffix letter “X” to the ordering code.

The multiple input dataheet allow parallel expansion to a 1-of decoder using just three F devices or a 1-of decoder using four F devices and one inverter.
Please note that this diagram is provided only for the understanding of logic operations and should not 74t138 used to estimate propagation delays. Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, and c whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury to the user.
A critical component in any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect its safety or effectiveness. This device is ideally suited for high-speed bipolar memory.
Either voltage limit or current limit is sufficient to protect inputs.
