描述 Description

The NTS0308E is an 8-bit, dual supply translating transceiver family with auto direction sensing that enables bidirectional voltage level translation.
It features eight 1-bit input-output ports (A and B), one output enable input (OE) and two supply pins (VCC(A) and VCC(B)).
VCC(A) can be supplied at any voltage between 0.95 V and 3.6 V.
VCC(B) can be supplied at any voltage between 1.65 V and 5.5 V.
This flexibility makes the device suitable for translating between any of the voltage nodes (0.95 V, 1.2 V, 1.8 V, 2.5 V, 3.3 V and 5.0 V). VCC(A) must be ≤ VCC(B) to ensure proper operation.
Pins A and OE are referenced to VCC(A) and pin B is referenced to VCC(B). A LOW level at pin OE causes the outputs to assume a high-impedance OFF-state.

特性 Features
