# 74HC4052DRG

**HANSCHIP semiconductor** · Analog Switches, Multiplexers · SOP-16

74HC4052DRG from HANSCHIP semiconductor, in a SOP-16. 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 | Y0B | bidirectional | Independent input/output of switch B channel 0, with signal range VEE to VDD. |
| 2 | Y2B | bidirectional | Independent input/output of switch B channel 2, with signal range VEE to VDD. |
| 3 | ZB | bidirectional | Common input/output of switch B, connected to the selected Y channel, with signal range VEE to VDD. |
| 4 | Y3B | bidirectional | Independent input/output of switch B channel 3, with signal range VEE to VDD. |
| 5 | Y1B | bidirectional | Independent input/output of switch B channel 1, with signal range VEE to VDD. |
| 6 | ~E | input | Active-low enable input; low lets A0/A1 select one channel, high turns all switches off regardless of A0 and A1. |
| 7 | VEE | power_in | Negative supply voltage, recommended -6.0 V to 0 V with VDD-VEE not exceeding 9 V; normally tied to VSS for digital multiplexing. |
| 8 | VSS | power_in | Ground supply for the digital control inputs (A0, A1, enable), usually connected to ground. |
| 9 | A1 | input | Select input A1 which, with A0, chooses the active channel for both switches. |
| 10 | A0 | input | Select input A0 which, with A1, chooses the active channel for both switches. |
| 11 | Y3A | bidirectional | Independent input/output of switch A channel 3, with signal range VEE to VDD. |
| 12 | Y0A | bidirectional | Independent input/output of switch A channel 0, with signal range VEE to VDD. |
| 13 | ZA | bidirectional | Common input/output of switch A, connected to the selected Y channel, with signal range VEE to VDD. |
| 14 | Y1A | bidirectional | Independent input/output of switch A channel 1, with signal range VEE to VDD. |
| 15 | Y2A | bidirectional | Independent input/output of switch A channel 2, with signal range VEE to VDD. |
| 16 | VDD | power_in | Positive supply voltage, recommended 3.0 V to 9.0 V (absolute maximum 12 V). |
