LMH7324SQ

Texas Instruments · Comparators · WQFN-32(5x5)

LMH7324SQ from Texas Instruments, in a WQFN-32(5x5). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCCOA power_in Positive supply for output stage A, independent of the input stage supply, allowing output levels of different logic families.
2 ~{QA} output Inverted output A, with output levels determined by the choice of VCCOA.
3 QA output Output A, with output levels determined by the choice of VCCOA.
4 VEEA power_in Negative supply A; all four VEE pins are circular connected together via two antiparallel diodes.
5 VEEB power_in Negative supply B; all four VEE pins are circular connected together via two antiparallel diodes.
6 QB output Output B, with output levels determined by the choice of VCCOB.
7 ~{QB} output Inverted output B, with output levels determined by the choice of VCCOB.
8 VCCOB power_in Positive supply for output stage B, independent of the input stage supply, allowing output levels of different logic families.
9 VCCIB power_in Positive supply for input stage B, independent of the output stage supply; VCCI and VCCO share the same ground pin VEE.
10 INB- input Negative input B for analog voltages between 200 mV below VEE and 2V below VCCI.
11 INB+ input Positive input B for analog voltages between 200 mV below VEE and 2V below VCCI.
12 VEEB power_in Negative supply B; all four VEE pins are circular connected together via two antiparallel diodes.
13 VEEC power_in Negative supply C; all four VEE pins are circular connected together via two antiparallel diodes.
14 INC+ input Positive input C for analog voltages between 200 mV below VEE and 2V below VCCI.
15 INC- input Negative input C for analog voltages between 200 mV below VEE and 2V below VCCI.
16 VCCIC power_in Positive supply for input stage C, independent of the output stage supply; VCCI and VCCO share the same ground pin VEE.
17 VCCOC power_in Positive supply for output stage C, independent of the input stage supply, allowing output levels of different logic families.
18 ~{QC} output Inverted output C, with output levels determined by the choice of VCCOC.
19 QC output Output C, with output levels determined by the choice of VCCOC.
20 VEEC power_in Negative supply C; all four VEE pins are circular connected together via two antiparallel diodes.
21 VEED power_in Negative supply D; all four VEE pins are circular connected together via two antiparallel diodes.
22 QD output Output D, with output levels determined by the choice of VCCOD.
23 ~{QD} output Inverted output D, with output levels determined by the choice of VCCOD.
24 VCCOD power_in Positive supply for output stage D, independent of the input stage supply, allowing output levels of different logic families.
25 VCCID power_in Positive supply for input stage D, independent of the output stage supply; VCCI and VCCO share the same ground pin VEE.
26 IND- input Negative input D for analog voltages between 200 mV below VEE and 2V below VCCI.
27 IND+ input Positive input D for analog voltages between 200 mV below VEE and 2V below VCCI.
28 VEED power_in Negative supply D; all four VEE pins are circular connected together via two antiparallel diodes.
29 VEEA power_in Negative supply A; all four VEE pins are circular connected together via two antiparallel diodes.
30 INA+ input Positive input A for analog voltages between 200 mV below VEE and 2V below VCCI.
31 INA- input Negative input A for analog voltages between 200 mV below VEE and 2V below VCCI.
32 VCCIA power_in Positive supply for input stage A, independent of the output stage supply; VCCI and VCCO share the same ground pin VEE.
33 DAP passive Central pad at the bottom of the package that transfers heat out of the part; it is electrically isolated and may be connected to any voltage within the part's allowed range, commonly the lowest supply.
