DIP16 ORDERING NUMBER : L293B

DESCRIPTION The L293B and L293E are quad push-pull drivers capableof delivering output currents to 1A per channel. Each channel is controlledby a TTL-compatible logic input and each pair of drivers (a full bridge) is equipped with an inhibit input which turns off all four transistors. A separate supply input is provided for the logic so that it may be run off a lower voltage to reduce dissipation. Additionally, the L293E has external connection of sensing resistors, for …ver más…

Figure 12 :Example of P.C. Board Copper Area which is Used as Heatsink During soldering the pins temperature must not exceed 260oC and the soldering time must not be longer than 12 seconds. The external heatsink or printed circuit copper area must be connected to electrical ground. Figure 13 :External Heatsink Mounting Example (Rth = 30oC/W)
