TLC074CPWPR

Texas Instruments · Operational Amplifier · HTSSOP-20-EP

TLC074CPWPR from Texas Instruments, in a HTSSOP-20-EP. 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	1OUT	output	Channel 1 output, high-drive stage rated for IOH 57 mA at VDD − 1.5 V and IOL 55 mA at 0.5 V.
2	1IN−	input	Channel 1 inverting input; common-mode input range is 0.5 V to VDD − 0.8 V.
3	1IN+	input	Channel 1 non-inverting input; common-mode input range is 0.5 V to VDD − 0.8 V.
4	VDD	power_in	Positive supply, 4.5 V to 16 V single supply (±2.25 V to ±8 V split), absolute maximum 17 V.
5	2IN+	input	Channel 2 non-inverting input; common-mode input range is 0.5 V to VDD − 0.8 V.
6	2IN−	input	Channel 2 inverting input; common-mode input range is 0.5 V to VDD − 0.8 V.
7	2OUT	output	Channel 2 output, high-drive stage rated for IOH 57 mA at VDD − 1.5 V and IOL 55 mA at 0.5 V.
8	NC	unconnected	No internal connection.
9	NC	unconnected	No internal connection.
10	NC	unconnected	No internal connection.
11	NC	unconnected	No internal connection.
12	NC	unconnected	No internal connection.
13	NC	unconnected	No internal connection.
14	3OUT	output	Channel 3 output, high-drive stage rated for IOH 57 mA at VDD − 1.5 V and IOL 55 mA at 0.5 V.
15	3IN−	input	Channel 3 inverting input; common-mode input range is 0.5 V to VDD − 0.8 V.
16	3IN+	input	Channel 3 non-inverting input; common-mode input range is 0.5 V to VDD − 0.8 V.
17	GND	power_in	Negative supply/ground; all voltages except differential voltages are referenced to GND.
18	4IN+	input	Channel 4 non-inverting input; common-mode input range is 0.5 V to VDD − 0.8 V.
19	4IN−	input	Channel 4 inverting input; common-mode input range is 0.5 V to VDD − 0.8 V.
20	4OUT	output	Channel 4 output, high-drive stage rated for IOH 57 mA at VDD − 1.5 V and IOL 55 mA at 0.5 V.
21	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).

Symbol: TLC074CPWPR
Footprint: Package_SO:TSSOP-20-1EP_4.4x6.5mm_P0.65mm_EP2.15x3.35mm
3D model: HTSSOP-20-EP, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.2 mm nominal TSSOP 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: tlc074cpwpr-etched.step / tlc074cpwpr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlc074cpwpr.step / tlc074cpwpr.glb are the bare package body.
