GMT G2129TB1U SOT-23-6 21+ 原装现货
1-2-3 -4位双向电压电平转换器带有自动方向传感和±15kV ESD保护
General Description
This 4-bit noninverting translator uses two separate
configurable power-supply rails. The A port is
designed to track VCCA. VCCA accepts any supply
voltage from 1.2V to 3.6V. The B port is designed
to track VCCB. VCCB accepts any supply voltage
from 1.65V to 5.5V. This allows for universal
low-voltage bidirectional translation between any
of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5V voltage
nodes. VCCA should not exceed VCCB.
When the output-enable (OE) input is low, all
outputs are placed in the high-impedance state.
To ensure the high-impedance state during
power up or power down, OE should be tied to
GND through a pulldown resistor; the minimum
value of the resistor is determined by the current-
sourcing capability of the driver.
The G2129 is designed so that the OE input circuit
is supplied by VCCA.
This device is fully specified for partial-power-down
applications using Ioff. The Ioff circuitry disables
the outputs, preventing damaging current backflow
through the device when it is powered
down.
