10 / 18 page www.ti.com Absolute Maximum Ratings (1) Recommended Operating Conditions (1) SN74SSTU32864C 25-BIT CONFIGURABLE REGISTERED BUFFER WITH SSTL_18 INPUTS AND OUTPUTS SCES542A – JANUARY 2004 – REVISED FEBRUARY 2005 over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VCC Supply voltage range –0.5 2.5 V VI Input voltage range(2)(3) –0.5 2.5 V VO Output voltage range(2)(3) –0.5 VCC + 0.5 V IIK Input clamp current VI < 0 or VI > VCC ±50 mA IOK Output clamp current VO < 0 or VO > VCC ±50 mA IO Continuous output current VO = 0 to VCC ±50 mA Continuous current through each VCC or GND ±100 mA θ JA Package thermal impedance(4) 36 °C/W Tstg Storage temperature range –65 150 °C (1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. 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. (2) The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. (3) This value is limited to 2.5 V maximum. (4) The package thermal impendance is calculated in accordance with JESD 51-7. MIN NOM MAX UNIT VCC Supply voltage 1.7 1.9 V VREF Reference voltage 0.49 × V CC 0.5 × V CC 0.51 × V CC V VI Input voltage 0 VCC V VIH AC high-level input voltage Data inputs, CSR VREF + 250 mV V VIL AC low-level input voltage Data inputs, CSR VREF – 250 mV V VIH DC high-level input voltage Data inputs, CSR VREF + 125 mV V VIL DC low-level input voltage Data inputs, CSR VREF – 125 mV V VIH High-level input voltage RESET, Cn 0.65 × V CC V VIL Low-level input voltage RESET, Cn 0.35 × V CC V VICR Common-mode input voltage range CLK, CLK 0.675 1.125 V VI(PP) Peak-to-peak input voltage CLK, CLK 600 mV IOH High-level output current –8 mA IOL Low-level output current 8 mA TA Operating free-air temperature 0 70 °C (1) The RESET and Cn inputs of the device must be held at valid logic voltage levels (not floating) to ensure proper device operation. The differential inputs must not be floating, unless RESET is low. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004. 10 |
