Description (Output Current = 2 mA + (2 mA × D[3:0])
A[1:0] = 0 selects OUT0. D[3:0] = b0100 sets OUT0 current to 2 mA + (2 mA × 4) = 10 mA.
A[1:0] = 0 selects OUT0. D[3:0] = b1000 sets OUT0 current to 2 mA + (2 mA × 8) = 18 mA.
A[1:0] = b10 selects OUT2. D[3:0] = b1101 sets OUT2 current to 2 mA + (2 mA × 13) = 28 mA.
A[1:0] = b11 selects OUT3. D[3:0] = b0000 sets OUT3 current to 2 mA + (2 mA × 0) = 2 mA.
Description
A[3] = 1 enables OUT3. D[3] = 0 connects IN2 to OUT3.
A[3] = 1 enables OUT3. D[3] = 1 connects IN3 to OUT3.
A[3:2] = b11 enables OUT2 and OUT3. D[3:2] = b00 connects IN2 to both OUT2 and OUT3.
A[3:2] = b11 enables OUT2 and OUT3. D[3:2] = b10 connects IN2 to OUT2 and connects IN3
to OUT3.
A[1] = 1 enables OUT1. D[1] = 0 connects IN0 to OUT1.
D[1:0] = b11 enables OUT0 and OUT1. D[1:0] = b11 connects IN1 to both OUT0 and OUT1.
A[3:0] = b1111 enables all outputs. D[3:0] = b0101 connects IN2 to OUT3, IN3 to OUT2, IN0 to
OUT1, IN1 to OUT0.
A[1:0] = 0 selects OUT0. D2 = 1 enables OUT0. D[1:0] = 0 connects IN0 to OUT0.
A[1:0] = 0 selects OUT0. D2 = 0 disables OUT0. D[1:0] = 0 connects IN0 to OUT0.
A[1:0] = b10 selects OUT2. D2 = 1 enables OUT2. D[1:0] = b01 connects IN1 to OUT2.
A[1:0] = b11 selects OUT3. D2 = 1 enables OUT3. D[1:0] = b00 connects IN0 to OUT3.
