TYPICAL APPLICATIONS
10A, T2L COMPATIBLE, SOLID
STATE RELAY
Use of the 4N40 for high sensi-
tivity, 5300 V isolation capability,
provides this highly reliable solid
state relay design. This design is
compatible with 74, 74S and 74H
series T2L logic systems inputs
and 220V AC loads up to 10A.

470 Ω
25W, LOGIC INDICATOR LAMP DRIVER
The high surge capability and non-reactive input
characteristics of the 4N40 allow it to directly couple,
without buffers, T2L and DTL logic to indicator alarm
devices, without danger of introducing noise and
logic glitches.

400V SYMMETRICAL TRANSISTOR COUPLER
Use of the high voltage PNP portion of the 4N40 provides a 400V transistor
capable of conducting positive and negative signals with current transfer
ratios of over 1%. This function is useful in remote instrumentation, high volt-
age power supplies and test equipment. Care should be taken not to exceed
the 40mW power dissipation rating when used at high voltages.
