Description
Power supply ground.
Single-ended output. LVCMOS/LVTTL interface levels.
HCSL receiver and driver direction select pin. When HIGH, selects the
IN-to-QA/nQA path. When LOW, selects the QA/nQA-to-QB path.
LVCMOS/LVTTL interface levels.
Single-ended signal input. LVCMOS/LVTTL interface levels.
An external fixed precision resistor (475Ω) from this pin to ground provides a
reference current used for differential current-mode QA/nQA outputs.
Power supply pin.
Differential transceiver pair. HCSL interface levels.
NOTE: Pullup and Pulldown refer to internal input resistors. See Table 2, Pin Characteristics, for typical values.

Absolute Maximum Ratings
NOTE: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device.
These ratings are stress specifications only. Functional operation of product at these conditions or any conditions beyond
those listed in the DC Characteristics or AC Characteristics is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect product reliability.
