GTLP16T1655MTD

Revised January 2005 GTLP16T1655 16-Bit LVTTL/GTLP Universal Bus Transceiver with High Drive GTLP and Individual Byte Controls General Description Features The GTLP16T1655 is a 16-bit universal bus transceiver that provides LVTTL to GTLP signal level translation. It allows for transparent, latched and clocked modes of data transfer. The device provides a high speed interface between cards operating at LVTTL logic levels and a backplane operating at GTLP logic levels. High speed backplane operation is a direct result of GTLP’s reduced output swing ( VCC +50 mA ESD Rating >2000V Storage Temperature (TSTG) −24 mA A Port VI < 0V A Port +24mA B Port +100 mA −40°C to +85°C Operating Temperature (TA) Note 5: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum rating. The “Recommended Operating Conditions” table will define the conditions for actual device operation. −65°C to +150°C Note 6: IO Absolute Maximum Rating must be observed. Note 7: VTT and Rterm can be adjusted to accommodate backplane impedances other than 50Ω, within the boundaries of not exceeding the DC Absolute IOL ratings (200 mA). Similarly VREF can be adjusted to compensate for changes in VTT. DC Electrical Characteristics Over Recommended Operating Free-Air Temperature Range, VREF = 1.0V (unless otherwise noted).
