NOTES: (1) Pins 1, 2, 28—Schmitt-Trigger input without pull-up and -down

resistor. (2) Pins 3-5, 16-21, 27—Schmitt-Trigger input without pull-up and

-down resistor. (3) Pins 10-15—Schmitt-Trigger input without pull-up and

-down resistor. (4) Pins 3-5, 15-20, 27—these pins are invalid when MODE

(pin 10) is HIGH. (5) Pins 11-13—these pins have different functions corre-

sponding to MODE (pin 10) HIGH/LOW.

PIN CONFIGURATION

ELECTROSTATIC

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown

recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling

and installation procedures can cause damage.

ESD damage can range from subtle performance degradation

to complete device failure. Precision integrated circuits may

be more susceptible to damage because very small parametric

changes could cause the device not to meet its published

specifications.
