TYPICAL APPLICATIONS
10A, T²L COMPATIBLE, SOLID
STATE RELAY
Use of the H11C4 for high sensitiv-
ity, 5300 V isolation capability,
provides this highly reliable solid

H11CX
state relay design. This design is
"COIL"
compatible with 74, 74S and 74H
series T²L logic systems inputs
56K
and 120V AC (H11C1, H11C2,
H11C3) or 220V AC (H11C4,
H11C5, H11C6) loads up to 10A.

25W, LOGIC INDICATOR LAMP DRIVER
The high surge capability and non-reactive input characteris-
470 Ω
tics of the H11C allow it to directly couple, without buffers,
+5V
T²L and DTL logic to indicator alarm devices, without danger

200V/400V SYMMETRICAL TRANSISTOR COUPLER
Use of the high voltage PNP portion of the H11C provides a 400V transistor capable of
conducting positive and negative signals with current transfer ratios of over 1%. This function _INPUT
is useful in remote instrumentation, high voltage power supplies and test equipment. Care
should be taken not to exceed the H11C 400mW power dissipation rating when used at high
voltages.
