.
N-channel source-follower high side drivers and NPN-based
output drivers have parasitic diodes which remain reverse-
biased with VDD at 0V and output voltages above ground.
These output types will not conduct until the E-B or S-B
diodes break down, typically above 7V.
The HS-26C31RH line driver is produced in a radiation hard-
ened CMOS process but uses a NPN bipolar output driver to
provide both high output drive and power-off output isolation.
The output can be run from ground to over 6V without signif-
icant leakage, with the supply off, unlike standard CMOS
logic types. This allows the outputs of active and inactive
drivers to be paralleled without complications.
The HS-26C32RH line receiver has an input structure which
provides a
±
10V maximum input signal range with respect to
device ground. The input impedance of the receiver is typi-
cally 10,000
, with no clamping devices at the pin. A pow-
ered-down device simply adds its input impedance in parallel
to the other devices on the line.
A curve tracer can demonstrate the difference in behavior
between a standard CMOS input and output with power off
and the HS-26C31/32RH devices’ line inputs and outputs.
The inactive CMOS devices clamp whatever line they are
attached to at less than a volt, drawing many milliamperes.
The line pins of the Intersil RS-422 chip set are well-
behaved, acting as a three-state output and a 10k
input.
