General Description

Features

Continuous brightness control

The MM5450 and MM5451 are monolithic MOS integrated

circuits utilizing N-channel metal-gate low thresholdꢁ en-

hancement modeꢁ and ion-implanted depletion mode devic-

esꢂ They are available in 40-pin molded or cavity dual-in-line

packagesꢂ The MM5450ꢀMM5451 is designed to drive com-

mon anode-separate cathode LED displaysꢂ A single pin

controls the LED display brightness by setting a reference
