Single-supply octal-translating transceiver with tri-state outputs

The SN74LV8T245 is an octal bus

transceiver with 3-state outputs. All eight

channels are controlled by the direction (DIR) pin

and output enable ( OE) pin.

The output level is referenced to the supply

voltage (V CC) and supports 1.8-V,

2.5-V, 3.3-V, and 5-V CMOS levels.

The input is designed with a lower threshold

circuit to support up translation for lower

voltage CMOS inputs (for example, 1.2 V input to

1.8 V output or 1.8 V input to 3.3 V output).

Additionally, the 5-V tolerant input pins enable

down translation (for example, 3.3 V to 2.5 V

output).
