TI SN754410 Quadruple Half H driver
Output Clamp Diodes for inductive Transient Suppresion!
1-A Output Current capabiltiy per driver
TTL and CMOS compatible high impedance diode clamped inputs
thermal shutdown
internal ESD protection
three state output
Sink/Source interlock circuitry prevents simultaneous conduction
no Output "glitch" during power-Up or Power-down

*Improved Functional Replacement for the SGS L293D..

Hope that helps
