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
Using any one of the drive circuits in Figures 15-17 with
I
W70L AND ACPL-K73L, as long as the PC board layout
practices are followed. 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 current at a constant level to minimize ground
shifting for other devices connected to the input-supply
ground.

Figure 17. CMOS gate drive circuit for ACPL-W70L families.
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, where the resistor is recommended to
connect to the anode of the LED, may be used.
