onsemi · Translators, Level Shifters · TSSOP-24

74LVX3245MTCX from onsemi, in a TSSOP-24. 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 (3V side) supply, recommended 2.7V to 3.6V; power it up first.
2 T/R input Transmit/Receive input: HIGH sends A to B, LOW sends B to A; should ramp with VCCA.
3 A0 bidirectional Side A (3V bus) data input or 3-STATE output, 0V to VCCA.
4 A1 bidirectional Side A (3V bus) data input or 3-STATE output, 0V to VCCA.
5 A2 bidirectional Side A (3V bus) data input or 3-STATE output, 0V to VCCA.
6 A3 bidirectional Side A (3V bus) data input or 3-STATE output, 0V to VCCA.
7 A4 bidirectional Side A (3V bus) data input or 3-STATE output, 0V to VCCA.
8 A5 bidirectional Side A (3V bus) data input or 3-STATE output, 0V to VCCA.
9 A6 bidirectional Side A (3V bus) data input or 3-STATE output, 0V to VCCA.
10 A7 bidirectional Side A (3V bus) data input or 3-STATE output, 0V to VCCA.
11 GND power_in Ground.
12 GND power_in Ground.
13 GND power_in Ground.
14 B7 bidirectional Side B (5V bus) data input or 3-STATE output, 0V to VCCB.
15 B6 bidirectional Side B (5V bus) data input or 3-STATE output, 0V to VCCB.
16 B5 bidirectional Side B (5V bus) data input or 3-STATE output, 0V to VCCB.
17 B4 bidirectional Side B (5V bus) data input or 3-STATE output, 0V to VCCB.
18 B3 bidirectional Side B (5V bus) data input or 3-STATE output, 0V to VCCB.
19 B2 bidirectional Side B (5V bus) data input or 3-STATE output, 0V to VCCB.
20 B1 bidirectional Side B (5V bus) data input or 3-STATE output, 0V to VCCB.
21 B0 bidirectional Side B (5V bus) data input or 3-STATE output, 0V to VCCB.
22 OE input Active-low Output Enable input; when HIGH, both A and B ports are in high impedance; should ramp with or ahead of VCCA.
23 NC unconnected No connect.
24 VCCB power_in B-port (5V side) supply, recommended 4.5V to 5.5V.
