When using multiple-input and multiple-channel logic devices inputs must not ever be left floating. In many cases, functions or parts of functions of digital logic devices are unused; for example, when only 24 channels of a 32-channel D-type latch are used. Pins with bus-hold circuitry (xDy) are automatically held in a valid state and can be left unconnected without the input voltage floating. Other inputs, such as the xLE and x OE must be terminated at either ground or VCC to prevent floating. Generally, the inputs are tied to GND or VCC, whichever makes more sense for the logic function or is more convenient.
It is not recommended to use pull-up or pull-down resistors with bus-hold inputs.
