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 negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. This value is limited to 4.6 V maximum. 3. The package thermal impedance is calculated in accordance with JESD 51. recommended operating conditions MIN MAX UNIT VCC Supply voltage 3 3.6 V IOH‡ High-level output current –25 mA IOL‡ Low-level output current 25 mA ∆t/∆v Input transition rise or fall rate Outputs enabled 5 ns/V TA Operating free-air temperature –40 85 °C ‡ Refer to Figures 1 and 2 for typical I/O ranges. electrical characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP§ MAX UNIT VIK AorB ports VCC =3V II = 18 mA 3.7 VCC+1.2 V VIK A or B ports VCC = 3 V II = –18 mA –0.9 –1.2 V Control inputs VCC = 3.6 V, VI = VCC or GND ±10 µA VI =VCC OE low 0.4 0.6 mA II AorB ports VCC =3 6V VI = VCC OE high 25 µA A or B ports VCC = 3.6 V VI =0 OE low –0.7 –1 mA VI = 0 OE high –60 µA IOZH VCC = 3.6 V, VO = 3 V 0.7 20 µA IOZL VCC = 3.6 V, VO = 0.5 V –0.2 –50 µA ICC/buffer VCC = 3.6 V, IO = 0, VI = VCC or GND 3.7 5.6 mA ICCZ VCC = 3.6 V, Control inputs = VCC or GND 0.8 mA ∆ICC¶ VCC = 3 V to 3.6 V, One input at VCC – 0.6 V, Other inputs at VCC or GND 600 µA Ci VI = 3 V or 0 3.5 pF Cio VO = 3 V or 0 7.5 pF § All typical values are at VCC = 3.3 V, TA = 25°C. ¶ This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND. |
