SN74LVTH2245DWR

Texas Instruments · Latches · SOIC-20-300mil

SN74LVTH2245DWR 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 DIR input Direction control: low selects B-to-A transfer and high selects A-to-B transfer, per the function table.
2 A1 bidirectional A-port data I/O; recommended IOH is -32 mA and IOL is 64 mA for the SN74LVTH2245 A port.
3 A2 bidirectional A-port data I/O; recommended IOH is -32 mA and IOL is 64 mA for the SN74LVTH2245 A port.
4 A3 bidirectional A-port data I/O; recommended IOH is -32 mA and IOL is 64 mA for the SN74LVTH2245 A port.
5 A4 bidirectional A-port data I/O; recommended IOH is -32 mA and IOL is 64 mA for the SN74LVTH2245 A port.
6 A5 bidirectional A-port data I/O; recommended IOH is -32 mA and IOL is 64 mA for the SN74LVTH2245 A port.
7 A6 bidirectional A-port data I/O; recommended IOH is -32 mA and IOL is 64 mA for the SN74LVTH2245 A port.
8 A7 bidirectional A-port data I/O; recommended IOH is -32 mA and IOL is 64 mA for the SN74LVTH2245 A port.
9 A8 bidirectional A-port data I/O; recommended IOH is -32 mA and IOL is 64 mA for the SN74LVTH2245 A port.
10 GND power_in Ground reference pin for the device.
11 B8 bidirectional B-port data I/O with equivalent 22-ohm series resistors; designed to source or sink up to 12 mA, with recommended IOH of -12 mA and IOL of 12 mA.
12 B7 bidirectional B-port data I/O with equivalent 22-ohm series resistors; designed to source or sink up to 12 mA, with recommended IOH of -12 mA and IOL of 12 mA.
13 B6 bidirectional B-port data I/O with equivalent 22-ohm series resistors; designed to source or sink up to 12 mA, with recommended IOH of -12 mA and IOL of 12 mA.
14 B5 bidirectional B-port data I/O with equivalent 22-ohm series resistors; designed to source or sink up to 12 mA, with recommended IOH of -12 mA and IOL of 12 mA.
15 B4 bidirectional B-port data I/O with equivalent 22-ohm series resistors; designed to source or sink up to 12 mA, with recommended IOH of -12 mA and IOL of 12 mA.
16 B3 bidirectional B-port data I/O with equivalent 22-ohm series resistors; designed to source or sink up to 12 mA, with recommended IOH of -12 mA and IOL of 12 mA.
17 B2 bidirectional B-port data I/O with equivalent 22-ohm series resistors; designed to source or sink up to 12 mA, with recommended IOH of -12 mA and IOL of 12 mA.
18 B1 bidirectional B-port data I/O with equivalent 22-ohm series resistors; designed to source or sink up to 12 mA, with recommended IOH of -12 mA and IOL of 12 mA.
19 OE input Output enable: low enables the transfer path, high isolates the buses; tie OE to VCC through a pullup resistor to keep outputs high-impedance above 1.5 V.
20 VCC power_in Supply voltage pin; recommended operating range is 2.7 V to 3.6 V.
