TYPICAL APPLICATIONS

10A, T²L COMPATIBLE, SOLID

STATE RELAY

LOAD

Ω

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.

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.

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.
