L293B Description
The L293B devices are quad push-pull drivers that can deliver up to 1A per channel of output current. A TTL compatible logic input controls each channel, and each pair of drivers (a full bridge) has an inhibit input that switches off all four transistors. The logic has its own supply input, allowing it to run at a lower voltage and hence reduce dissipation.
L293B Features
CURRENT OUTPUT 1A PER CHANNEL
CURRENT PEAK OUTPUT 2A PER CHANNEL (non repetitive)
FACILITY TO PROHIBIT
IMMUNITY TO HIGH NOISE
LOGIC SUPPLY SEPARATE
PROTECTION FROM OVERHEATING
L293B Applications
L293B is intended for general use and can be used in a variety of situations.
