SGM4T245
4-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs
The SGM4T245 is a 4-bit, dual-supply bus transceiver with configurable voltage translation and 3-state outputs. The device can be used as two 2-bit transceivers or as a 4-bit transceiver. The nAn and nBn are four 2-bit input and output ports. nDIR are the direction control inputs and nOE are the output enable inputs. VCCA and VCCB are the supply pins. The supply voltage of VCCA and VCCB can range from 1.2V to 5.0V, making the device suitable for bidirectional translating between any of the 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5.0V voltage nodes.
Pins nAn, nOE and nDIR are referenced to VCCA and nBn pins are referenced to VCCB. When nDIR is set high, it allows transmission from nAn to nBn. When nDIR is set low, it allows transmission from nBn to nAn. nOE can be used to make the outputs disabled so that the buses are effectively isolated. In suspend mode, both nAn and nBn are in high-impedance state when either VCCA or VCCB input is at GND level.
This device is highly suitable for partial power-down applications using power-off leakage current (IOFF) circuit. When the device is powered down, the current backflow will be prevented from passing through the device.
OE should be tied to VCC through a pull-up resistor, in order to make sure the high-impedance state during power-up or power-down, the minimum resistance depends on the current-sinking capability of the driver.
