TPIC6B259DWR

Texas Instruments · Latches · SOIC-20-300mil

TPIC6B259DWR from Texas Instruments, in a SOIC-20-300mil. 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 NC unconnected No internal connection.
2 VCC power_in Logic supply voltage, recommended 4.5 V to 5.5 V (absolute maximum 7 V with respect to GND).
3 S0 input Latch-select address bit 0 (LSB) that selects which of the eight DMOS outputs is addressed; logic input range is -0.3 V to 7 V.
4 DRAIN0 output Open-drain power DMOS output rated 50 V drain-to-source, 150 mA continuous sink current, with 500 mA typical current limit at TC = 25°C.
5 DRAIN1 output Open-drain power DMOS output rated 50 V drain-to-source, 150 mA continuous sink current, with 500 mA typical current limit at TC = 25°C.
6 DRAIN2 output Open-drain power DMOS output rated 50 V drain-to-source, 150 mA continuous sink current, with 500 mA typical current limit at TC = 25°C.
7 DRAIN3 output Open-drain power DMOS output rated 50 V drain-to-source, 150 mA continuous sink current, with 500 mA typical current limit at TC = 25°C.
8 S1 input Latch-select address bit 1 that selects which of the eight DMOS outputs is addressed; logic input range is -0.3 V to 7 V.
9 GND power_in Ground reference for all voltages; the power DMOS sources are internally connected to GND.
10 GND power_in Ground reference for all voltages; the power DMOS sources are internally connected to GND.
11 GND power_in Ground reference for all voltages; the power DMOS sources are internally connected to GND.
12 S2 input Latch-select address bit 2 (MSB) that selects which of the eight DMOS outputs is addressed; logic input range is -0.3 V to 7 V.
13 G input Active-low enable; hold high (inactive) while the address lines change to avoid writing erroneous data into the latch.
14 DRAIN4 output Open-drain power DMOS output rated 50 V drain-to-source, 150 mA continuous sink current, with 500 mA typical current limit at TC = 25°C.
15 DRAIN5 output Open-drain power DMOS output rated 50 V drain-to-source, 150 mA continuous sink current, with 500 mA typical current limit at TC = 25°C.
16 DRAIN6 output Open-drain power DMOS output rated 50 V drain-to-source, 150 mA continuous sink current, with 500 mA typical current limit at TC = 25°C.
17 DRAIN7 output Open-drain power DMOS output rated 50 V drain-to-source, 150 mA continuous sink current, with 500 mA typical current limit at TC = 25°C.
18 D input Data input written into the addressed latch; setup and hold times are 20 ns minimum relative to the rising edge of G.
19 CLR input Active-low clear; when low, all DMOS outputs are off and unaffected by the address and data inputs.
20 NC unconnected No internal connection.
