DS55493 Product details

Description

The DS55493 DS75493 is a quad LED segment driver It is designed to interface between MOS IC’s and LED’s An external resistor is required for each segment to drive the output current which is approximately equal to 0 7V RL and is relatively constant independent of supply variations Blanking can be achieved by taking the chip enable (CE) to a logical ‘‘1’’ level
