ICL8052/ICL7104, ICL8068/ICL7104
Positive Supply Voltage: Nominally +15V.
Digital Ground: 0V, ground return.
Status Output: HI during integrate and deintegrate until data is latched. LO when analog section
is in auto-zero configuration.
Polarity: Three-state output. HI for positive input.
Over Range: Three-state output.
Most Significant Bit (MSB).
DATA Bits: Three-state outputs. See Table 3 for format of ENABLES and bytes. HIGH = true.
Least Significant Bit (LSB).
LOW BYTE ENABLE: If not in handshake mode (see pin 27) when LO (with CE/LD, pin 30)
activates low-order byte outputs, BITS 1-8. When in handshake mode (see pin 27), serves as a
low byte flag output. See Figures 11, 12, 13.
MID BYTE ENABLE: Activates Bits 9-16, see LBEN (pin 22)
HIGH BYTE ENABLE: Activates Bits 9-14, POL, OR, see LBEN (pin 22)
HIGH BYTE ENABLE: Activates POL, OR, see LBEN (pin 22).
RC oscillator pin: Can be used as clock output.
