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 should have a good bypass capacitor to prevent power disturbance. A 0.1-

μF capacitor is

recommended for devices with a single supply. If there are multiple Vcc pins then a 0.01-

μF or 0.022-μF

capacitor is recommended for each power pin. It is acceptable 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 should not ever float. In many cases, functions or parts of functions

of digital logic devices are unused; for example, when only two inputs of a triple-input AND gate are used or only

3 of the 4 buffer gates are used. Such input pins should not be left unconnected because the undefined voltages

at the outside connections result in undefined operational states. Specified below are the rules that must be

observed under all circumstances. All unused inputs of digital logic devices must be connected to a high or low

bias to prevent them from floating. The logic level that should be applied to any particular unused input depends

on the function of the device. Generally, they will be tied to Gnd or Vcc, whichever is more convenient.
