SN74LVCC3245ADWR

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

SN74LVCC3245ADWR 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, operating range 2.3 V to 3.6 V; if VCCA is below 100 mV or floating, all I/O outputs are disabled and go high-impedance.
2 DIR input Direction control input referenced to VCCA; low transfers data from the B bus to the A bus and high transfers data from the A bus to the B bus (with OE low).
3 A1 bidirectional A1 port data I/O, tracking VCCA (2.3 V to 3.6 V).
4 A2 bidirectional A2 port data I/O, tracking VCCA (2.3 V to 3.6 V).
5 A3 bidirectional A3 port data I/O, tracking VCCA (2.3 V to 3.6 V).
6 A4 bidirectional A4 port data I/O, tracking VCCA (2.3 V to 3.6 V).
7 A5 bidirectional A5 port data I/O, tracking VCCA (2.3 V to 3.6 V).
8 A6 bidirectional A6 port data I/O, tracking VCCA (2.3 V to 3.6 V).
9 A7 bidirectional A7 port data I/O, tracking VCCA (2.3 V to 3.6 V).
10 A8 bidirectional A8 port data I/O, tracking VCCA (2.3 V to 3.6 V).
11 GND power_in Ground reference; the datasheet states ground should be applied first during power-up.
12 GND power_in Ground reference pin.
13 GND power_in Ground reference pin.
14 B8 bidirectional B8 port data I/O, tracking VCCB (3 V to 5.5 V).
15 B7 bidirectional B7 port data I/O, tracking VCCB (3 V to 5.5 V).
16 B6 bidirectional B6 port data I/O, tracking VCCB (3 V to 5.5 V).
17 B5 bidirectional B5 port data I/O, tracking VCCB (3 V to 5.5 V).
18 B4 bidirectional B4 port data I/O, tracking VCCB (3 V to 5.5 V).
19 B3 bidirectional B3 port data I/O, tracking VCCB (3 V to 5.5 V).
20 B2 bidirectional B2 port data I/O, tracking VCCB (3 V to 5.5 V).
21 B1 bidirectional B1 port data I/O, tracking VCCB (3 V to 5.5 V).
22 OE input Output enable, active low; when high the device is isolated (A and B ports disabled), and the control circuitry is powered from VCCA.
23 NC unconnected No internal connection.
24 VCCB power_in B-port supply voltage, operating range 3 V to 5.5 V; if VCCB is below 100 mV or floating, all I/O outputs are disabled and go high-impedance.
