PI3B3257QEX

Diodes Incorporated · Signal Switches, Multiplexers, Decoders · QSOP-16-150mil

PI3B3257QEX from Diodes Incorporated, in a QSOP-16-150mil. 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	S	input	Select input that chooses the I0 (S = 0) or I1 (S = 1) data input of the quad 2:1 mux; control inputs can be driven up to +3.6V regardless of supply voltage.
2	IA0	input	Data input A0 of the A channel, connected to YA when S = 0 and E is LOW; absolute maximum DC input voltage is -0.5V to +4.6V.
3	IA1	input	Data input A1 of the A channel, connected to YA when S = 1 and E is LOW; absolute maximum DC input voltage is -0.5V to +4.6V.
4	YA	output	Multiplexed data output A, set to Hi-Z when E is HIGH; switch on-resistance is typically 5Ω.
5	IB0	input	Data input B0 of the B channel, connected to YB when S = 0 and E is LOW; absolute maximum DC input voltage is -0.5V to +4.6V.
6	IB1	input	Data input B1 of the B channel, connected to YB when S = 1 and E is LOW; absolute maximum DC input voltage is -0.5V to +4.6V.
7	YB	output	Multiplexed data output B, set to Hi-Z when E is HIGH; switch on-resistance is typically 5Ω.
8	GND	power_in	Ground reference for the device; absolute maximum supply voltage to ground potential is -0.5V to +4.6V.
9	YC	output	Multiplexed data output C, set to Hi-Z when E is HIGH; switch on-resistance is typically 5Ω.
10	IC1	input	Data input C1 of the C channel, connected to YC when S = 1 and E is LOW; absolute maximum DC input voltage is -0.5V to +4.6V.
11	IC0	input	Data input C0 of the C channel, connected to YC when S = 0 and E is LOW; absolute maximum DC input voltage is -0.5V to +4.6V.
12	YD	output	Multiplexed data output D, set to Hi-Z when E is HIGH; switch on-resistance is typically 5Ω.
13	ID1	input	Data input D1 of the D channel, connected to YD when S = 1 and E is LOW; absolute maximum DC input voltage is -0.5V to +4.6V.
14	ID0	input	Data input D0 of the D channel, connected to YD when S = 0 and E is LOW; absolute maximum DC input voltage is -0.5V to +4.6V.
15	E	input	Enable input: when HIGH all outputs are disabled to Hi-Z, and when LOW the selected inputs are connected to the outputs; control inputs can be driven up to +3.6V regardless of supply voltage.
16	VCC	power_in	3.3V supply (VCC = 3.3V ±10% over the operating range of -40°C to +85°C); absolute maximum supply voltage is +4.6V.
