124 / 144 page  10.0 Device Characteristics (Continued) 124 www.national.com Revision 1.2 10.2.4 Input, PCI 3.3V Compatible Symbol: INPCI 10.2.5 Analog Input Symbol: AI 10.2.6 Output, TTL/CMOS Compatible, Push-Pull Buffer Symbol: Op/n Output, TTL/CMOS Compatible, rail-to-rail push-pull buffer that is capable of sourcing p mA and sinking n mA 10.2.7 Output, TTL/CMOS Compatible, Open-Drain Buffer Symbol: ODn Output, TTL/CMOS-compatible open-drain output buffer capable of sinking n mA. Output from these signals is open- drain and is never forced high. Symbol Parameter Conditions Min Max Unit VIH Input High Voltage 0.5 VDD VDD + 0.5 1 1. Not tested. Guaranteed by design. V VIL Input Low Voltage −0.51 0.3 VDD V lIL 2 2. Input leakage current includes the output leakage of the bi-directional buffers with TRI-STATE outputs. Input Leakage Current 0 < VIN <VDD3 ±13 3. Maximum 20 µA for all pins together (for exceptions, refer to Section 10.2.11 on page 125.). Not tested. Guaran- teed by characterization. µA Symbol Parameter Conditions Min Max Unit VIR Input Voltage Range 0 5.51 1. Not tested. Guaranteed by characterization. V lIL Input Leakage Current VIN =VIR 3002 2. This buffer type is excluded from the pins for which the total pins leakage of the device is maximum 20 µA. Not tested. Guaranteed by characterization. µA Symbol Parameter Conditions Min Max Unit VOH Output High Voltage IOH = −p mA 2.4 V IOH = −50 µA VSUP − 0.2 1 1. VSUP is VDD3 or VSB3 according to the output power well. V VOL Output Low Voltage IOL = n mA 0.4 V IOL =50 µA 0.2 V Symbol Parameter Conditions Min Max Unit VOL Output Low Voltage IOL = n mA 0.4 V IOL =50 µA 0.2 V |
