MM5450中文资料LED Display Driver数据手册Microchip规格书

描述 Description

The MM5450 and MM5451 LED display drivers are monolithic MOS ICs fabricated in an N-Channel, metal-gate process. The technology produces low-threshold, enhancement-mode, and ion-implanted depletion-mode devices.A single pin controls the LED display brightness by setting a reference current through a variable resistor connected to the supply.

特性 Features

Continuous brightness control
Serial data input
No load signal requirement
Enable (on MM5450)
Wide power supply operation
TTL compatibility
34 or 35 outputs, 15mA capability
Alphanumeric capability
