DM74LS47MX datasheet

 

Description

The DM74LS47, DM74LS47MX accepts four lines of BCD (8421) input data, generates their complements internally and decodes the data with seven AND/OR gates having open-collector outputs to drive indicator segments directly. Each segment output is guaranteed to sink 24 mA in the ON (LOW) state and withstand 15V in the OFF (HIGH) state with a maximum leakage current of 250 µA. Auxiliary inputs provided blanking, lamp test and cascadable zero-suppression functions.

 

Features

1. Open-collector outputs

2. Drive indicator segments directly

3. Cascadable zero-suppression capability

4. Lamp test input

Absolute maximum ratings ( Ta=25°C )

1. Supply Voltage : 7V

2. Input Voltage : 7V

3. Operating Free Air Temperature Range : 0°C to +70°C

4. Storage Temperature Range : -65°C to +150°C

ILI9341 tft display

Description

ILI9341 is a 262,144-color single-chip SOC driver for a-TFT liquid crystal display with resolution of 240RGBx320 dots, comprising a 720-channel source driver, a 320-channel gate driver, 172,800 bytes GRAM for graphic display data of 240RGBx320 dots, and power supply circuit.

ILI9341 supports parallel 8-/9-/16-/18-bit data bus MCU interface, 6-/16-/18-bit data bus RGB interface and 3-/4-line serial peripheral interface (SPI). The moving picture area can be specified in internal GRAM by window address function. The specified window area can be updated selectively, so that moving picture can be displayed simultaneously independent of still picture area.
