SN74LVCC4245ADW

Texas Instruments · Translators, Level Shifters · SOIC-24-300mil

SN74LVCC4245ADW from Texas Instruments, in a SOIC-24-300mil. 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 VCCA power_in A-port supply voltage, with a recommended operating range of 4.5 V to 5.5 V.
2 DIR input Direction control input that selects the transfer direction (low: B data to A bus; high: A data to B bus) when OE is low, and is powered from VCCA.
3 A1 bidirectional A-port input/output channel 1, with A-side levels referenced to VCCA (4.5 V to 5.5 V).
4 A2 bidirectional A-port input/output channel 2, with A-side levels referenced to VCCA (4.5 V to 5.5 V).
5 A3 bidirectional A-port input/output channel 3, with A-side levels referenced to VCCA (4.5 V to 5.5 V).
6 A4 bidirectional A-port input/output channel 4, with A-side levels referenced to VCCA (4.5 V to 5.5 V).
7 A5 bidirectional A-port input/output channel 5, with A-side levels referenced to VCCA (4.5 V to 5.5 V).
8 A6 bidirectional A-port input/output channel 6, with A-side levels referenced to VCCA (4.5 V to 5.5 V).
9 A7 bidirectional A-port input/output channel 7, with A-side levels referenced to VCCA (4.5 V to 5.5 V).
10 A8 bidirectional A-port input/output channel 8, with A-side levels referenced to VCCA (4.5 V to 5.5 V).
11 GND power_in Ground reference pin; the datasheet lists GND pins 11, 12 and 13 as ground connections.
12 GND power_in Ground pin for the device, which should be connected to system ground.
13 GND power_in Ground reference pin; the datasheet lists GND pins 11, 12 and 13 as ground connections.
14 B8 bidirectional B-port input/output channel 8, with B-side levels referenced to VCCB (2.7 V to 5.5 V).
15 B7 bidirectional B-port input/output channel 7, with B-side levels referenced to VCCB (2.7 V to 5.5 V).
16 B6 bidirectional B-port input/output channel 6, with B-side levels referenced to VCCB (2.7 V to 5.5 V).
17 B5 bidirectional B-port input/output channel 5, with B-side levels referenced to VCCB (2.7 V to 5.5 V).
18 B4 bidirectional B-port input/output channel 4, with B-side levels referenced to VCCB (2.7 V to 5.5 V).
19 B3 bidirectional B-port input/output channel 3, with B-side levels referenced to VCCB (2.7 V to 5.5 V).
20 B2 bidirectional B-port input/output channel 2, with B-side levels referenced to VCCB (2.7 V to 5.5 V).
21 B1 bidirectional B-port input/output channel 1, with B-side levels referenced to VCCB (2.7 V to 5.5 V).
22 OE input Active-low output enable; when high, the device is placed in isolation and the bus is disconnected.
23 NC unconnected No internal connection.
24 VCCB power_in B-port supply voltage, with a recommended operating range of 2.7 V to 5.5 V.
