TPIC6A595NE

Texas Instruments · Shifting Register · PDIP-20

TPIC6A595NE from Texas Instruments, in a PDIP-20. 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 DRAIN2 output Open-drain DMOS output 2, rated 50V with 350mA continuous sink current and chopping current limit for short-circuit protection.
2 DRAIN3 output Open-drain DMOS output 3, rated 50V with 350mA continuous sink current and chopping current limit for short-circuit protection.
3 SRCLR input Shift register clear, active low; a low level clears the shift register.
4 G input Output enable, active low; high turns all drain outputs off, low makes storage register data transparent to the output buffer.
5 PGND power_in Power ground, internally connected to the other PGND pins and to be connected externally to power system ground to minimize parasitic impedance.
6 PGND power_in Power ground, internally connected to the other PGND pins and to be connected externally to power system ground to minimize parasitic impedance.
7 RCK input Register clock; data transfers from shift register to storage register on its rising edge, and write/read data is valid only when RCK is low.
8 SRCK input Shift register clock; serial data shifts in on its rising edge.
9 DRAIN4 output Open-drain DMOS output 4, rated 50V with 350mA continuous sink current and chopping current limit for short-circuit protection.
10 DRAIN5 output Open-drain DMOS output 5, rated 50V with 350mA continuous sink current and chopping current limit for short-circuit protection.
11 DRAIN6 output Open-drain DMOS output 6, rated 50V with 350mA continuous sink current and chopping current limit for short-circuit protection.
12 DRAIN7 output Open-drain DMOS output 7, rated 50V with 350mA continuous sink current and chopping current limit for short-circuit protection.
13 SEROUT output Serial data output for cascading to the SER IN pin of the next device.
14 LGND power_in Logic ground, to be connected externally at a single point to PGND so as to reduce crosstalk between logic and load circuits.
15 PGND power_in Power ground, internally connected to the other PGND pins and to be connected externally to power system ground to minimize parasitic impedance.
16 PGND power_in Power ground, internally connected to the other PGND pins and to be connected externally to power system ground to minimize parasitic impedance.
17 VCC power_in Logic supply voltage, recommended 4.5V to 5.5V (absolute maximum 7V).
18 SERIN input Serial data input to the 8-bit shift register, sampled on the rising edge of SRCK.
19 DRAIN0 output Open-drain DMOS output 0, rated 50V with 350mA continuous sink current and chopping current limit for short-circuit protection.
20 DRAIN1 output Open-drain DMOS output 1, rated 50V with 350mA continuous sink current and chopping current limit for short-circuit protection.
