By using the recommended circuit in Figure 13, good
CMR can be achieved. The balanced I

CMR with Other Drive Circuits
CMR performance with drive circuits other than that
shown in Figure 13 may be enhanced by following these
guidelines:
1. Use of drive circuits where current is shunted from the
2. Use of I
Figure 15 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-sinking capability.
It also helps maintain the driving-gate power-supply cur-
rent at a constant level to minimize ground shifting for
other devices connected to the input-supply ground.
When using an open-collector TTL or open-drain CMOS
logic gate, the circuit in Figure 16 may be used. When
using a CMOS gate to drive the optocoupler, the circuit
shown in Figure 17 may be used. The diode in parallel
