GMT G2129TB1U SOT-23-6 21+ 原装现货

　　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.

　　Features

　　1.2V to 3.6V on A port and 1.65V to 5.5V on

　　B port (VCCA ≤ VCCB)

　　VCC Isolation Feature-If Either VCC Input Is at

　　GND, All Outputs Are in the High-Impedance

　　State

　　OE Input Circuit Referenced to VCCA

　　Low Power Consumption, 5μA Max ICC

　　No Power-Supply Sequencing Required-Either

　　VCCA or VCCB Can be Ramped First

　　Ioff Supports Partial-Power-Down Mode
