Ray 74hct244pw-q100: CAD wording names the Adom_Gen land, not KiCad official cae3769

74HCT244PW-Q100

Nexperia USA Inc. · Integrated Circuits (ICs) · TSSOP-20

74HCT244PW-Q100 from Nexperia USA Inc., in a TSSOP-20. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). The symbol is generated from that pin table and the footprint is an Adom_Gen land derived from the manufacturer drawing; the 3D model is generated to fit it.

Pinout

Pin Name Type Function
1 1OE input Active-LOW output enable for outputs 1Y0 to 1Y3; a HIGH on nOE forces these outputs into the high-impedance OFF-state.
2 1A0 input Data input for buffer channel 1A0; inputs include clamp diodes so current-limiting resistors can interface them to voltages above VCC.
3 2Y0 tri_state Non-inverting 3-state bus output 2Y0, high-impedance when 2OE is HIGH.
4 1A1 input Data input for buffer channel 1A1; inputs include clamp diodes so current-limiting resistors can interface them to voltages above VCC.
5 2Y1 tri_state Non-inverting 3-state bus output 2Y1, high-impedance when 2OE is HIGH.
6 1A2 input Data input for buffer channel 1A2; inputs include clamp diodes so current-limiting resistors can interface them to voltages above VCC.
7 2Y2 tri_state Non-inverting 3-state bus output 2Y2, high-impedance when 2OE is HIGH.
8 1A3 input Data input for buffer channel 1A3; inputs include clamp diodes so current-limiting resistors can interface them to voltages above VCC.
9 2Y3 tri_state Non-inverting 3-state bus output 2Y3, high-impedance when 2OE is HIGH.
10 GND power_in Ground (0 V) reference for all device voltages; this is the device ground pin.
11 2A3 input Data input for buffer channel 2A3; inputs include clamp diodes so current-limiting resistors can interface them to voltages above VCC.
12 1Y3 tri_state Non-inverting 3-state bus output 1Y3, high-impedance when 1OE is HIGH.
13 2A2 input Data input for buffer channel 2A2; inputs include clamp diodes so current-limiting resistors can interface them to voltages above VCC.
14 1Y2 tri_state Non-inverting 3-state bus output 1Y2, high-impedance when 1OE is HIGH.
15 2A1 input Data input for buffer channel 2A1; inputs include clamp diodes so current-limiting resistors can interface them to voltages above VCC.
16 1Y1 tri_state Non-inverting 3-state bus output 1Y1, high-impedance when 1OE is HIGH.
17 2A0 input Data input for buffer channel 2A0; inputs include clamp diodes so current-limiting resistors can interface them to voltages above VCC.
18 1Y0 tri_state Non-inverting 3-state bus output 1Y0, high-impedance when 1OE is HIGH.
19 2OE input Active-LOW output enable for outputs 2Y0 to 2Y3; a HIGH on nOE forces these outputs into the high-impedance OFF-state.
20 VCC power_in Supply voltage; 4.5 V to 5.5 V for the 74HCT244-Q100 (2.0 V to 6.0 V applies to the 74HC244-Q100 variant).
