2-bit LVTTL to GTL transceiver

8.

Limiting values

[1]

The input and output negative voltage ratings may be exceeded if the input and output clamping 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.

Recommended operating conditions

Table 5.

Limiting values

In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
