... Application Information General Description The EL5000A is a high performance 70V TFT-LCD row driver. It level shifts TTL level timing signals from the video source into 70V peak to peak output voltage. Its output is capable of delivering 100mA peak current into 1nF of capacitive load. It also incorporates logic to control the output timings ...
