10 Power Supply Recommendations

The power supply can be any voltage between the min and max supply voltage rating located in the

Recommended Operating Conditions table.

Each VCC pin must have a good bypass capacitor in order to prevent power disturbance. For devices with a

single supply, a 0.1-

μF capacitor is recommended and if there are multiple VCC pins then a 0.01-μF or 0.022-μF

capacitor is recommended for each power pin. It is ok to parallel multiple bypass caps to reject different

frequencies of noise. 0.1-

μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be

installed as close to the power pin as possible for best results.

11 Layout

11.1 Layout Guidelines

When using multiple bit logic devices, inputs must never float. In many cases, functions or parts of functions of

digital logic devices are unused. Examples include when only two inputs of a triple input and gate are used or

when only three of the four buffer gates are used. Avoid leaving input pins unconnected because the undefined

voltages at the outside connections result in undefined operational states. Observe the following rules under all

circumstances. Connect all unused inputs of digital logic devices to a high or low bias to prevent them from

floating. Based on the function of the device, apply the logic level to any unused input. Based on convenience, tie

unused inputs to the GND or the VCC.
