name: SN74HC02 alias: SN54HC02 variations: SOIC, SSOP, PDIP, SO, TSSOP, CDIP # variant W (ceramic dual flatpack) is too exotic (body goes through the board) # there is also a FK (20 pin LCCC) variant, but since the pin 1 is not QFN standard, QEDA does not support it description: quadruple 2-input positive-NOR gates datasheet: https://www.ti.com/lit/ds/symlink/sn74hc02.pdf pinout: 1: 1Y: 1 1A: 2 1B: 3 2: 2Y: 4 2A: 5 2B: 6 3: 3Y: 10 3A: 8 3B: 9 4: 4Y: 13 4A: 11 4B: 12 GND: 7 VCC: 14 properties: power: VCC ground: GND input: 1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B output: 1Y, 2Y, 3Y, 4Y schematic: symbol: ic left: 1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B right: 1Y, 2Y, 3Y, 4Y top: VCC bottom: GND housing@SOIC: suffix: D outline: JEDEC MS-012 AB housing@SSOP: suffix: DB outline: JEDEC MO-150 housing@PDIP: suffix: N outline: JEDEC MS-001 AA housing@SO: suffix: NS pattern: SOP leadCount: 14 pitch: 1.27 bodyWidth: 5.0-5.6 bodyLength: 9.9-10.50 height: 2.0 leadWidth: 0.31-0.51 leadLength: 0.55-1.05 leadHeight: 0.25 leadSpan: 7.4-8.2 housing@TSSOP: suffix: PW outline: JEDEC MO-153 AB-1 housing@CDIP: suffix: J pattern: DIP leadCount: 14 pitch: 2.54 # e bodyWidth: 6.22-7.19 # B bodyLength: 19.15-19.94 # A height: 5.08 # C leadWidth: 0.36-0.66 leadLength: 3.3 leadHeight: 0.2-0.36 leadSpan: 7.83-7.97
