SN74HCS05QDRQ1

Texas Instruments · Inverters · SOIC-14

SN74HCS05QDRQ1 from Texas Instruments, in a SOIC-14. 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	1A	input	Input A of channel 1 (Schmitt-trigger CMOS input, VCC supply range 2 V to 6 V).
2	1Y	output	Open-drain output Y of channel 1; it can only drive low and is high-impedance when high, so a pull-up resistor is needed to define the high level.
3	2A	input	Input A of channel 2 (Schmitt-trigger CMOS input).
4	2Y	output	Open-drain output Y of channel 2; it can only drive low and is high-impedance when high.
5	3A	input	Input A of channel 3 (Schmitt-trigger CMOS input).
6	3Y	output	Open-drain output Y of channel 3; it can only drive low and is high-impedance when high.
7	GND	power_in	Ground reference; the ground must sink the total output current plus the maximum ICC.
8	4Y	output	Open-drain output Y of channel 4; it can only drive low and is high-impedance when high.
9	4A	input	Input A of channel 4 (Schmitt-trigger CMOS input).
10	5Y	output	Open-drain output Y of channel 5; it can only drive low and is high-impedance when high.
11	5A	input	Input A of channel 5 (Schmitt-trigger CMOS input).
12	6Y	output	Open-drain output Y of channel 6; it can only drive low and is high-impedance when high.
13	6A	input	Input A of channel 6 (Schmitt-trigger CMOS input).
14	VCC	power_in	Positive supply; the recommended operating range is 2 V to 6 V (absolute maximum 7 V).
