SN74HC283N

lingxingic · Specialty Logic · DIP-16

SN74HC283N from lingxingic, in a DIP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 S2 output Sum output bit 2. Represents the second bit of the binary sum of A + B + CIN. Push-pull CMOS output.
2 B2 input B operand input bit 2. CMOS-level logic input for the second bit of the B operand.
3 A2 input A operand input bit 2. CMOS-level logic input for the second bit of the A operand.
4 S1 output Sum output bit 1 (LSB). Represents the least-significant bit of the binary sum of A + B + CIN.
5 A1 input A operand input bit 1 (LSB). CMOS-level logic input for the least-significant bit of the A operand.
6 B1 input B operand input bit 1 (LSB). CMOS-level logic input for the least-significant bit of the B operand.
7 CIN input Carry input. Incoming carry bit added to the A+B sum. Tie to GND (active-HIGH operation) or VCC (active-LOW operation) when no carry-in is intended; used when cascading multiple SN74HC283 devices for wider-than-4-bit addition.
8 GND power_in Ground reference (0 V). All input and output voltages are referenced to this pin.
9 COUT output Carry output. Outgoing carry bit resulting from A + B + CIN. Connect to the CIN of the next-higher SN74HC283 stage when cascading to build wider adders.
10 S4 output Sum output bit 4 (MSB). Represents the most-significant bit of the 4-bit binary sum.
11 B4 input B operand input bit 4 (MSB). CMOS-level logic input for the most-significant bit of the B operand.
12 A4 input A operand input bit 4 (MSB). CMOS-level logic input for the most-significant bit of the A operand.
13 S3 output Sum output bit 3. Represents the third bit of the binary sum of A + B + CIN.
14 A3 input A operand input bit 3. CMOS-level logic input for the third bit of the A operand.
15 B3 input B operand input bit 3. CMOS-level logic input for the third bit of the B operand.
16 VCC power_in Positive supply voltage. Operating range 2.0 V to 6.0 V (SN74HC283); absolute maximum 7.0 V. Bypass with a 100 nF ceramic capacitor to GND.
