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 can be exceeded if the input and output clamp current ratings are observed. 2. This value is limited to 4.6 V maximum. recommended operating conditions ′ALVC7804-25 VCC = 3.3 V " 0.3 V ′ALVC7804-40 VCC = 3.3 V " 0.3 V UNIT MIN MAX MIN MAX VIH High-level input voltage 2 2 V VIL Low-level input voltage 0.8 0.8 V VI 0 VCC 0 VCC V VO 0 VCC 0 VCC V IOH High-level output current, VCC =3V 8 8 mA IOH g, Q outputs, Flags VCC = 3 V – 8 – 8 mA IOL Low-level output current, VCC =3V 16 16 mA IOL , Q outputs, Flags VCC = 3 V 16 16 mA fclock Clock frequency 40 25 MHz D0 – D17 high or low 8 12 LDCK high or low 8 12 tw Pulse duration UNCK high or low 8 12 ns PEN low 8 12 RESET low 10 12 D0 – D17 before LDCK ↑ 5 5 tsu Setup time LDCK inactive before RESET high 6 6 ns PEN before LDCK ↑ 8 8 D0 – D17 after LDCK ↑ 0 0 th Hold time PEN high after LDCK low 0 0 ns th Hold time PEN low after LDCK ↑ 3 3 ns LDCK inactive after RESET high 6 6 TA Operating free-air temperature 0 70 0 70 °C |
