Driver and Receiver Outputs
To minimize bus loading, these devices also feature a
TTL Compatible Driver and Control Inputs and
schottky diode in series with the open collector output
Receiver Outputs
that isolates the driver output capacitance in the
disabled state. The output low voltage is typically “1V”
and the output high level is intended to be 2V. This is
achieved by terminating the bus with a pull up resistor
to 2V at both ends. The device can drive an
equivalent DC load of 18.5
Ω (or greater) in the above
configuration.
These signaling requirements, including a 1 volt
signal swing, low output capacitance and precise
receiver
thresholds
are

as
Bus
Transceiver Logic (BTL).
