Darlington Driver (UDN2901A)
The UDN2901A is a 16-pin chip which contains seven '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 UDN2901A create module but the BCX38C darlington transistor create modules (low-side switch) may potentially be used instead (shown connected to buzzer).
