For transients occurring when the LED is on, common-
mode rejection (CMR

CMR can be achieved. (In the case of the -261N families,
a minimum CMR of 15 kV/µs is guaranteed using this cir-

CMR with Other Drive Circuits
CMR performance with drive circuits other than that
shown in Figure 20 may be enhanced by following these
guidelines:
1. Use of drive circuits where current is shunted from
2. Use of I
Using any one of the drive circuits in Figures 22-24 with

HCPL-261N family, as long as the PC board layout prac-
tices are followed. Figure 22 shows a circuit which can
be used with any totem-pole-output TTL/LSTTL/HCMOS
logic gate. The buffer PNP transistor allows the circuit to
be used with logic devices which have low current-sink-
ing capability. It also helps maintain the driving-gate
power-supply current at a constant level to minimize
ground shifting for other devices connected to the in-
put-supply ground.
When using an open-collector TTL or open-drain CMOS
logic gate, the circuit in Figure 23 may be used. When
using a CMOS gate to drive the optocoupler, the circuit
shown in Figure 24 may be used. The diode in parallel
