GTL2107
12-bit GTL−/GTL/GTL+ to LVTTL translator
9. Limiting values
[1] The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
[2] Current into any output in the LOW state.
[3] Current into any output in the HIGH state.
[4] The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability. The maximum junction temperature of this integrated circuit should not exceed 150 °C.
10. Recommended operating conditions
Table 10. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
Voltages are referenced to GND (ground = 0 V).
