An internal pullup resistor from pin 1 to pin 4 allows active output if pin 1 is left open. *Note: A 0.01µF capacitor should be placed between VDD (Pin 4) and GND (Pin 2) to minimize power supply line noise. *Drawing is for reference to critical specifications defined by size measurements. Certain non-critical visual attributes, such as side castellations, reference pin shape, etc. may vary. All specifications subject to change without notice. • Enable / Disable Function Pin 1 OUTPUT (Pin 3) OPEN 2 ACTIVE '1' Level Vih ≥ 70% Vdd ACTIVE '0' Level Vil ≤ 30% Vdd High Z Fox Electronics 5570 Enterprise Parkway Fort Myers, Florida 33905 An Integrated Device Technology, Inc. company USA +1.239.693.0099 FOXonline.com FAX +1.239.693.1554
