2 / 17 page ML2264 2 PIN# NAME FUNCTION PIN# NAME FUNCTION 1 A IN 4 Analog input 4. 2 A IN 3 Analog input 3. 3 A IN 2 Analog input 2. 4 A IN 1 Analog input 1. 5 MODE Mode select input. MODE = GND: RD mode MODE = VCC: WR-RD mode Pin has internal current source pulldown to GND. 6 DB0 Data output — bit 0 (LSB). 7 DB1 Data output — bit 1. 8 DB2 Data output — bit 2. 8 DB3 Data output — bit 3. 10 RD Read input. In RD mode, this pin initiates a conversion. In WR-RD mode, this pin latches data into output latches. See Digital Interface section. 11 INT Interrupt output. This output signals the end of a conversion and indicates that data is valid on the data outputs. See Digital Interface section. 12 GND Ground. 13 –VREF Negative reference voltage for A/D converter. 14 +VREF Positive reference voltage for A/D converter. PIN DESCRIPTION 15 WR/RDY Write input or ready output. In WR-RD mode, this pin is WR input. In RD mode, this pin is RDY open drain output. See Digital Interface section. 16 CS Chip select input. This pin must be held low for the device to perform a conversion. 17 DB4 Data output — bit 4. 18 DB5 Data output — bit 5. 19 DB6 Data output — bit 6. 20 DB7 Data output — bit 7 (MSB). 21 A1 Digital address input 1 that selects analog input channel. See multiplexer addressing section. 22 A0 Digital address input 0 that selects analog input channel. See multiplexer addressing section. 23 SH/TH S/H, T/H mode select. When SH/TH = VCC, the device is in sample and hold mode. When SH/TH = GND, the device is in track and hold mode. Pin has internal pulldown current source to GND. 24 VCC Positive supply. +5 volts ± 5%. ABSOLUTE MAXIMUM RATINGS Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied.
