SN74S1051PWR

Texas Instruments · Specialty Logic · TSSOP-16

SN74S1051PWR from Texas Instruments, in a TSSOP-16. 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 VCC power_in Positive clamp supply connection for the diode array, one of two VCC pins (pins 1 and 16); the datasheet gives no supply voltage range, only that the diodes clamp to VCC and/or GND.
2 D01 passive Array diode terminal D01 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
3 D02 passive Array diode terminal D02 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
4 D03 passive Array diode terminal D03 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
5 D04 passive Array diode terminal D04 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
6 D05 passive Array diode terminal D05 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
7 D06 passive Array diode terminal D06 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
8 GND power_in Ground clamp connection for the diode array, one of two GND pins (pins 8 and 9); total current through all GND or VCC terminals is limited to 170 mA continuous and 1 A repetitive peak.
9 GND power_in Ground clamp connection for the diode array, one of two GND pins (pins 8 and 9); total current through all GND or VCC terminals is limited to 170 mA continuous and 1 A repetitive peak.
10 D07 passive Array diode terminal D07 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
11 D08 passive Array diode terminal D08 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
12 D09 passive Array diode terminal D09 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
13 D10 passive Array diode terminal D10 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
14 D11 passive Array diode terminal D11 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
15 D12 passive Array diode terminal D12 clamps to VCC or GND, with continuous forward current limited to 50 mA per terminal and repetitive peak forward current of 200 mA (tw ≤ 100 µs, duty cycle ≤ 20%).
16 VCC power_in Positive clamp supply connection for the diode array, one of two VCC pins (pins 1 and 16); the datasheet gives no supply voltage range, only that the diodes clamp to VCC and/or GND.
