These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace length of zero. recommended operating conditions SN54HC266 SN74HC266 UNIT MIN NOM MAX MIN NOM MAX UNIT VCC Supply voltage 2 5 6 2 5 6 V VCC = 2 V 1.5 1.5 VIH High-level input voltage VCC = 4.5 V 3.15 3.15 V VCC = 6 V 4.2 4.2 VCC = 2 V 0 0.5 0 0.5 VIL Low-level input voltage VCC = 4.5 V 0 1.35 0 1.35 V VCC = 6 V 0 1.8 0 1.8 VI Input voltage 0 VCC 0 VCC V VO Output voltage 0 VCC 0 VCC V VCC = 2 V 0 1000 0 1000 tt Input transition (rise and fall) time VCC = 4.5 V 0 500 0 500 ns VCC = 6 V 0 400 0 400 TA Operating free-air temperature –55 125 –40 85 °C electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS VCC TA = 25°C SN54HC266 SN74HC266 UNIT PARAMETER TEST CONDITIONS VCC MIN TYP MAX MIN MAX MIN MAX UNIT IOH VI = VIH or VIL, VO = VCC 6 V 0.01 0.5 10 5 µA 2 V 0.002 0.1 0.1 0.1 IOL = 20 µA 4.5 V 0.001 0.1 0.1 0.1 VOL VI = VIH or VIL 6 V 0.001 0.1 0.1 0.1 V IOL = 4 mA 4.5 V 0.17 0.26 0.4 0.33 IOL = 5.2 mA 6 V 0.15 0.26 0.4 0.33 II VI = VCC or 0 6 V ±0.1 ±100 ±1000 ±1000 nA ICC VI = VCC or 0, IO = 0 6 V 2 40 20 µA Ci 2 V to 6 V 3 10 10 10 pF PRODUCT PREVIEW information concerns products in the formative or design phase of development.
