* Specification same as SDM862/863/872/873J, A, R grades.
NOTES: (1) Measured at the same and hold output. (2) Measured with all input channels grounded. (3) The range of voltage on any input with respect to common over
which accuracy and leakage current is guaranteed. (4) Applicable over full operating temperature range. NO MISSING CODES GUARANTEED OVER TEMPERATURE
RANGE. (5) Adjustable to zero using external potentiometer or select-on-test resistor. (6) Specifications are at +25°C and measured at 50% level of transition. (7) When
using TTL drivers a 1kΩ pull-up resistor should be used. (8) Muxes operate in a break-before-make manner.
