8-Bit Dual-Supply Bus Transceiver with Configurable Voltage Translation and 3-State Outputs
The SGM8T245 is an 8-bit, dual-supply bus transceiver with configurable voltage translation and 3-state outputs. The An and Bn are 8-bit data input and output ports, DIR is the direction control input and OE is an output enable input. 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 An, OE and DIR are referenced to VCCA and Bn pins are referenced to VCCB. When DIR is set high, it allows transmission from An to Bn. When DIR is set low, it allows transmission from Bn to An. OE can be used to make the outputs disabled so that the buses are effectively isolated. In suspend mode, both An and Bn are in high-impedance state when either VCCA or VCCB input is at GND level.
This device is suitable for partial power-down applications using IOFF. When the device is powered down, it will protect against current backflow into the device and avoid damage to 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, and the minimum resistance depends on the current-sinking capability of the driver.
The SGM8T245 is available in Green TSSOP-24 and TQFN-5.5×3.5-24L packages. It operates over an ambient temperature range of -40℃ to +125℃.
