Nexperia · Analog Switches, Multiplexers · DHVQFN-16-EP(2.5x3.5)

74HC4851BQ-Q100 from Nexperia, in a DHVQFN-16-EP(2.5x3.5). 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 Y4 bidirectional Independent analog input/output channel 4, ON (low impedance to Z) only when E is LOW and S2, S1, S0 = H, L, L; high-impedance OFF when E is HIGH; switch voltage must stay between 0 V and VCC (absolute limit VCC + 0.5 V).
2 Y6 bidirectional Independent analog input/output channel 6, ON only when E is LOW and S2, S1, S0 = H, H, L; high-impedance OFF when E is HIGH; switch voltage must stay between 0 V and VCC.
3 Z bidirectional Common analog input/output that connects to the selected Yn channel when E is LOW; switch voltage must stay between 0 V and VCC.
4 Y7 bidirectional Independent analog input/output channel 7, ON only when E is LOW and S2, S1, S0 = H, H, H; high-impedance OFF when E is HIGH; switch voltage must stay between 0 V and VCC.
5 Y5 bidirectional Independent analog input/output channel 5, ON only when E is LOW and S2, S1, S0 = H, L, H; high-impedance OFF when E is HIGH; switch voltage must stay between 0 V and VCC.
6 E input Enable input, active LOW: LOW selects one channel per S2 to S0, HIGH puts all switches in the high-impedance OFF-state; input voltage must be between 0 V and VCC.
7 n.c. unconnected Not connected.
8 GND power_in Ground (0 V) reference for all voltages in the datasheet.
9 S2 input Select input, most significant bit of the channel select code (S2, S1, S0); input voltage must be between 0 V and VCC.
10 S1 input Select input, middle bit of the channel select code (S2, S1, S0); input voltage must be between 0 V and VCC.
11 S0 input Select input, least significant bit of the channel select code (S2, S1, S0); input voltage must be between 0 V and VCC.
12 Y3 bidirectional Independent analog input/output channel 3, ON only when E is LOW and S2, S1, S0 = L, H, H; high-impedance OFF when E is HIGH; switch voltage must stay between 0 V and VCC.
13 Y0 bidirectional Independent analog input/output channel 0, ON only when E is LOW and S2, S1, S0 = L, L, L; high-impedance OFF when E is HIGH; switch voltage must stay between 0 V and VCC.
14 Y1 bidirectional Independent analog input/output channel 1, ON only when E is LOW and S2, S1, S0 = L, L, H; high-impedance OFF when E is HIGH; switch voltage must stay between 0 V and VCC.
15 Y2 bidirectional Independent analog input/output channel 2, ON only when E is LOW and S2, S1, S0 = L, H, L; high-impedance OFF when E is HIGH; switch voltage must stay between 0 V and VCC.
16 VCC power_in Supply voltage: 2.0 V to 6.0 V recommended for 74HC4851-Q100 (4.5 V to 5.5 V for 74HCT4851-Q100), absolute maximum 7.0 V.
17 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: 74HC4851BQ-Q100
  • Footprint: Package_DFN_QFN:DHVQFN-16-1EP_2.5x3.5mm_P0.5mm_EP1x2mm
  • 3D model: DHVQFN-16-EP(2.5x3.5), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal VQFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: 74hc4851bq-q100-etched.step / 74hc4851bq-q100-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 74hc4851bq-q100.step / 74hc4851bq-q100.glb are the bare package body.
