Darlington Driver (UDN2981A)
The UDN2981A is an 18-pin chip which contains eight 'high-side switches' - The load connects between the transistor output and 0V and the transistor conducts current to V+ when turned on.
There is no specific UDN2981A create module but the BCX38C darlington transistor create modules (low-side switch) may potentially be used instead (shown connected to buzzer).
