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

SN74LVCZ245ADBR 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 that selects A-to-B transfer when high and B-to-A transfer when low; inputs accept voltages up to 5.5 V with VCC from 2.7 V to 3.6 V.
2 A1 bidirectional 3-state data port A1 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
3 A2 bidirectional 3-state data port A2 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
4 A3 bidirectional 3-state data port A3 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
5 A4 bidirectional 3-state data port A4 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
6 A5 bidirectional 3-state data port A5 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
7 A6 bidirectional 3-state data port A6 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
8 A7 bidirectional 3-state data port A7 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
9 A8 bidirectional 3-state data port A8 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
10 GND power_in Ground reference pin; all unused inputs must be held at VCC or GND to ensure proper device operation.
11 B8 bidirectional 3-state data port B8 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
12 B7 bidirectional 3-state data port B7 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
13 B6 bidirectional 3-state data port B6 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
14 B5 bidirectional 3-state data port B5 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
15 B4 bidirectional 3-state data port B4 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
16 B3 bidirectional 3-state data port B3 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
17 B2 bidirectional 3-state data port B2 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
18 B1 bidirectional 3-state data port B1 with IOL rated at 12 mA at 2.7 V and 24 mA at 3 V, and IOH rated at -12 mA at 2.7 V and -24 mA at 3 V.
19 OE input Active-low output-enable input; a high level places the A and B ports in isolation, and OE should be tied to VCC through a pullup resistor to hold the high-impedance state above 1.5 V.
20 VCC power_in Supply voltage pin, specified for operation from 2.7 V to 3.6 V.
