Clock Input: External clock or ocsillator.
Clock Output: Crystal or RC oscillator.
INPUT LO: Direct output mode where CE/LD, HBEN, MBEN and LBEN act as inputs directly
controlling byte outputs. If pulsed HI causes immediate entry into handshake mode (see Figure
13). If HI, enables CE/LD, HBEN, MBEN and LBEN as outputs. Handshake mode will be entered
and data output as in Figures 11 and 12 at conversion completion.
RUN/HOLD: Input HI conversions continuously performed every 2
pulses. Input LO conversion in progress completed, converter will stop in Auto-Zero 7 counts
before input integrate.
SEND ENABLE: Input controls timing of byte transmission in handshake mode. HI indicates
‘send’.
CHIP ENABLE/ LOAD: WITH MODE (PIN 27) LO, CE/LD serves as a master output enable;
when HI, the bit outputs and POL, OR are disabled. With MODE HI, pin serves as a LOAD strobe
(-ve going) used in handshake mode. See Figures 11 and 12.
Positive Logic Supply Voltage: Nominally +5V.
Analog Input: High Side.
Buffer Input: Buffer Analog to analog chip (ICL8052 or ICL8086).
Reference Capacitor: Negative Side.
Analog Ground: Input low side and reference low side.
Auto-Zero node.
Voltage Reference: Input (positive side).
Reference Capacitor: Positive side.
Comparator Input: From 8052/8068.
Negative Supply Voltage: Nominally -15V.
