Preliminary Datasheet

4-bit LVTTL to GTL transceiver

Note:

[1]

All typical values are measured at VCC = 3.3 V and Tamb = 25 °C.

[2]

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

[3]

This is the increase in supply current for each input that is at the specified TTL voltage level rather than VCC or GND.

Dynamic characteristics

All typical values are at VCC = 3.3 V and Tamb = 25 °C.
