SN74LS138D Frequently Asked Questions (FAQ)
-
The maximum operating frequency of the SN74LS138D is 25 MHz, but it can vary depending on the specific application and operating conditions.
-
To ensure proper decoupling, place a 0.1 μF ceramic capacitor between the VCC and GND pins of the SN74LS138D, and consider adding additional decoupling capacitors near the device.
-
The recommended input rise and fall time for the SN74LS138D is 10 ns to 20 ns to ensure proper operation and minimize errors.
-
No, the SN74LS138D is a 5V device and is not compatible with 3.3V systems. Using it in a 3.3V system may result in unreliable operation or damage to the device.
-
Unused inputs on the SN74LS138D should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
