NOTES: (1) Pins 10-15; Schmitt-Trigger input with pull-up resistor. (2) Pins

3-5, 16-20, 27; Schmitt-Trigger input with pull-down resister. (3) Pins 1, 2,

28; Schmitt-Trigger input. (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 corresponding to MODE (pin 10), (HIGH/LOW).

ELECTROSTATIC

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Texas Instru-

ments 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.
