Each output is a complete 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. The L293 and L293D are characterized for operation from 0°C to 70°C. Open-in-new Find other Brushed DC (BDC) motor drivers. Estimated Motor supply quiescent current: 90 - (3.16 +25) = 17 mA These boards also used a 74HC14 hex inverter chips (4 of 6 inverters used) to invert the input signal to one side of the H-bridge so that only one control signal was required per motor driver. For a LV8549MC based motor driver board. This circuit is a basic circuit for understanding the way of L293D H Bridge DC motor control with Arduino. Thereby it is a suitable device for obtaining variable DC by controlling the Motor speed.

A little late for my recent project work involving some 50 off L293D dual H-bridge IC's (some folks may also know of the approx. equivalent the SN754410) however I have just come across an alternative dual H-bridge IC being the LB1909MC.
http://www.onsemi.com/pub_link/Collateral/ENA2037-D.PDF
This is only available in a 10 pin SMD SOIC package format which is still solderable using 'normal' soldering irons with care. I have soldered SOIC chips from 8 pin to 32 pin successfully in the past.
There are seemingly a few advantages including:
1. No need for a separate 5Vdc logic supply
2. One input controls both sides of a H-bridge - so no need for an inverter to the other side
3. Far lower internal current draw than the L293D (ie 25 mA when En is high compared to 44 mA)
4. Output saturation voltage is lower (ie 0.5 V @ 400 mA compared to 1.2/1.4V @ 600 mA for L293D)
There is only 1 Output Enable pin to control both H-bridges.
So certainly an alternative IC that I will be considering and maybe experimenting with in the near future for bi-polar stepper motors and small low current DC motors requiring bi-directional control.
The only source I found at this time was Mouser.
