The SN74LS241N Tri-State Buffer allows you to toggle an output between the input and high-impedence. This is useful when working with 1-wire TTL interfaces such as the Dynamixel Servos.
This is a breakout board based on LS7366R quadrature counter IC. The Dual LS7366R buffer board makes it simple to keep track of the current position of the motors and the total distance traveled.
The ULN2003APG High Current Driver has 7 NPN Darlington arrays in a 16-SOIC package. This is perfect when you need to use a microcontroller to toggle a relay or control high power LEDs.
