SN74LVT245BDBR

Texas Instruments · Buffers, Drivers, Receivers, Transceivers · SSOP-20-208mil

SN74LVT245BDBR from Texas Instruments, in a SSOP-20-208mil. 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 input: a low level transfers B data to the A bus and a high level transfers A data to the B bus, per the function table.
2 A1 bidirectional A-bus 3-state input/output terminal 1, which drives or receives data on the A bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
3 A2 bidirectional A-bus 3-state input/output terminal 2, which drives or receives data on the A bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
4 A3 bidirectional A-bus 3-state input/output terminal 3, which drives or receives data on the A bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
5 A4 bidirectional A-bus 3-state input/output terminal 4, which drives or receives data on the A bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
6 A5 bidirectional A-bus 3-state input/output terminal 5, which drives or receives data on the A bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
7 A6 bidirectional A-bus 3-state input/output terminal 6, which drives or receives data on the A bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
8 A7 bidirectional A-bus 3-state input/output terminal 7, which drives or receives data on the A bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
9 A8 bidirectional A-bus 3-state input/output terminal 8, which drives or receives data on the A bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
10 GND power_in Device ground; per Note 5, all unused inputs must be held at VCC or GND to ensure proper operation.
11 B8 bidirectional B-bus 3-state input/output terminal 8, which drives or receives data on the B bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
12 B7 bidirectional B-bus 3-state input/output terminal 7, which drives or receives data on the B bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
13 B6 bidirectional B-bus 3-state input/output terminal 6, which drives or receives data on the B bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
14 B5 bidirectional B-bus 3-state input/output terminal 5, which drives or receives data on the B bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
15 B4 bidirectional B-bus 3-state input/output terminal 4, which drives or receives data on the B bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
16 B3 bidirectional B-bus 3-state input/output terminal 3, which drives or receives data on the B bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
17 B2 bidirectional B-bus 3-state input/output terminal 2, which drives or receives data on the B bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
18 B1 bidirectional B-bus 3-state input/output terminal 1, which drives or receives data on the B bus when OE is low; it is part of the 3.3-V ABT interface with 5-V tolerant inputs (VI up to 5.5 V).
19 OE input Active-low output enable: a high level isolates the A and B buses, and per the datasheet it should be tied to VCC through a pullup resistor to keep outputs high-impedance during power up and power down.
20 VCC power_in Supply voltage, recommended range 2.7 V to 3.6 V (3.3-V nominal operation).
