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).
PIN ASSIGNMENTSPIN CONFIGURATION
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.
