unused inputs must be connected to ground. Pull-down resistors (approximately 10 k Ω ) are recommended for inputs that are al-
lowed to ? oat while power is being applied to V S .

delay is in ? uenced by load conditions. Systems applications well below the speci ? ed output loading may require timing con-
siderations for some designs, i.e., multiplexed displays or when used in combination with sink drivers in a totem pole con ? guration.
