SN74CBT3253CDBQR from Texas Instruments, in a SSOP-16-150mil. 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 | S0 | input | Select address input bit 0 (VIL 0-0.8V, VIH 2-5.5V) that determines the data path in each multiplexer along with S1. |
| 2 | 1A | bidirectional | Multiplexer 1 A-port bidirectional data I/O (0-5.5V) that connects to the B port selected by S0 and S1 when 1OE is low. |
| 3 | 1B3 | bidirectional | Multiplexer 1 B3-port bidirectional data I/O that connects to 1A when S0=L, S1=H, and 1OE=L per function table. |
| 4 | 1B2 | bidirectional | Multiplexer 1 B2-port bidirectional data I/O that connects to 1A when S0=H, S1=L, and 1OE=L per function table. |
| 5 | 2OE | input | Multiplexer 2 active-low output enable control input that enables A-B data connection when low and high-impedance disconnect when high. |
| 6 | 1OE | input | Multiplexer 1 active-low output enable control input that enables A-B data connection when low and high-impedance disconnect when high. |
| 7 | 2B1 | bidirectional | Multiplexer 2 B1-port bidirectional data I/O that connects to 2A when S0=L, S1=L, and 2OE=L per function table. |
| 8 | GND | power_in | Ground (0V reference). |
| 9 | 1B1 | bidirectional | Multiplexer 1 B1-port bidirectional data I/O that connects to 1A when S0=L, S1=L, and 1OE=L per function table. |
| 10 | 1B4 | bidirectional | Multiplexer 1 B4-port bidirectional data I/O that connects to 1A when S0=H, S1=H, and 1OE=L per function table. |
| 11 | 2B2 | bidirectional | Multiplexer 2 B2-port bidirectional data I/O that connects to 2A when S0=H, S1=L, and 2OE=L per function table. |
| 12 | 2B3 | bidirectional | Multiplexer 2 B3-port bidirectional data I/O that connects to 2A when S0=L, S1=H, and 2OE=L per function table. |
| 13 | 2B4 | bidirectional | Multiplexer 2 B4-port bidirectional data I/O that connects to 2A when S0=H, S1=H, and 2OE=L per function table. |
| 14 | 2A | bidirectional | Multiplexer 2 A-port bidirectional data I/O (0-5.5V) that connects to the B port selected by S0 and S1 when 2OE is low. |
| 15 | S1 | input | Select address input bit 1 (VIL 0-0.8V, VIH 2-5.5V) that determines the data path in each multiplexer along with S0. |
| 16 | VCC | power_in | Supply voltage input, 4-5.5V operating range with 3 µA maximum quiescent current per Electrical Characteristics. |
