Turb0user, значит даташит ошибается

All inputs are TTL-compatible. Each output is acomplete totem-pole drive circuit with a Darlington
transistor sink and a pseudo-Darlington source.
Drivers are enabled in pairs with drivers 1 and 2
enabled by 1,2EN and drivers 3 and 4 enabled by
3,4EN. When an enable input is high, the
associated drivers are enabled, and their outputs
are active and in phase with their inputs. External
high-speed output clamp diodes should be used
for inductive transient suppression. When the
enable input is low, those drivers are disabled, and
their outputs are off and in a high-impedance
state. With the proper data inputs, each pair of
drivers form a full-H (or bridge) reversible drive
suitable for solenoid or motor applications.
