Trnasistor arrays for switching on XBee digotal output

Wireless & IoT
1

Hi,

I want to run a series of motors (small vibration motors that draw around 80 mA current) from the digital output pins of an XBee series1 module. Since these motors draw more currents than the XBee supports, I plan to power the motors independently (with a battery pack), and use a transistor as the switching device (with the output from the Xbee connected to the base, etc.).

There are 8 such pins and I dont want to connect 8 individual transistors, because that makes the circuit messy. I know there are transistor arrays availbale (multiple transistors on the same chip), but I dont know which ones to use.

Any recommendations on which transistor arrays I should use for my application?

regards,

A
