Function

1

NC

No Connect. Leave pin unconnected.

2

QA

One of two complementary outputs for Channel A. QA will be at logic high if the analog voltage at the

noninverting input is greater than the analog voltage at the inverting input (provided the comparator is

in the compare mode). See the LEA description (Pin 5) for more information.

3

QA

One of two complementary outputs for Channel A. QA will be at logic low if the analog voltage at the

noninverting input is greater than the analog voltage at the inverting input (provided the comparator is

in the compare mode). See the LEA description (Pin 5) for more information.

4

GND

Analog Ground

5

LEA

One of two complementary inputs for Channel A Latch Enable. In the compare mode (logic high), the

output will track changes at the input of the comparator. In the latch mode (logic low), the output will

reflect the input state just prior to the comparator’s being placed in the latch mode. LEA must be driven

in conjunction with LEA.

6

NC

No Connect. Leave pin unconnected or attach to GND (internally connected to GND).

7

LEA

One of two complementary inputs for Channel A Latch Enable. In the compare mode (logic low), the

output will track changes at the input of the comparator. In the latch mode (logic high), the output will

reflect the input state just prior to the comparator’s being placed in the latch mode. LEA must be driven

in conjunction with LEA.

8

Negative Supply Terminal

9

−INA

Inverting analog input of the differential input stage for Channel A. The inverting A input must be driven

in conjunction with the noninverting A input.

10

+INA

Noninverting analog input of the differential input stage for Channel A. The noninverting A input must

be driven in conjunction with the inverting A input.

11

NC

No Connect. Leave pin unconnected.

12

+INB

Noninverting analog input of the differential input stage for Channel B. The noninverting B input must

be driven in conjunction with the inverting B input.

13

−INB

Inverting analog input of the differential input stage for Channel B. The inverting B input must be driven

in conjunction with the noninverting B input.

14

Positive Supply Terminal

15

LEB

One of two complementary inputs for Channel B Latch Enable. In the compare mode (logic low), the

output will track changes at the input of the comparator. In the latch mode (logic high), the output will

reflect the input state just prior to the comparator’s being placed in the latch mode. LEB must be driven

in conjunction with LEB.

16

NC

No Connect. Leave pin unconnected or attach to GND (internally connected to GND).

17

LEB

One of two complementary inputs for Channel B Latch Enable. In the compare mode (logic high), the

output will track changes at the input of the comparator. In the latch mode (logic low), the output will

reflect the input state just prior to the comparator’s being placed in the latch mode. LEB must be driven

in conjunction with LEB.
