IntroductionThe SN74LVC245APWRG3 is a logic device from Texas Instruments (TI) that provides logic-level conversion between The Transistor–Transistor Logic (TTL) logic-level and the Low-Voltage CMOS (LVCMOS) logic level. The device is an octal bus transceiver with an integrated 3-State bus invert buffer. The device functions as two independent 4-bit buffers, each with separate Output Enable (OE) inputs and Output Enable (OE) outputs. The 3-State bus invert buffer can be used to convert data bits between differential channel and single-ended logic inputs/outputs. FeaturesThe SN74LVC245APWRG3 is an octal bus transceiver with an integrated 3-State bus invert buffer and contains eight non-inverting bidirectional buffers/drivers with 3-state outputs providing full voltage translation between TTL and LVCMOS levels. The SN74LVC245APWRG3 is designed to provide automatic interface between data lines of standard TTL levels and CMOS logic with VCC operating from 1.65V down to 1.2V. The integrated 3-State buffer features active low Output Enable (OE) inputs, separate active low Output Enable (OE) Outputs and a high level output impedance with improved rise/fall time characteristics. The devices have both Input and Output Schmitt-trigger action padding data transmission over HOT, noisier or longer bus lines. The SN74LVC245APWRG3 is available in a 28-pin SOIC package and is rated for operation over a temperature range of -40°C to +85°C.Logic-level compatibilityThe SN74LVC245APWRG3 is logic-level compatible with TTL logic and LVCMOS logic. This allows designers to mix and match different logic levels on the same data bus. The LVCMOS levels are a smaller output voltage than the standard TTL levels and this allows for tighter noise margins, lower power consumption and higher switching speed. The devices have both input and output Schmitt-trigger action adding data transmission over hot, noisier or longer bus lines.Application FieldThe SN74LVC245APWRG3 is an octal bus transceiver that can be used for a variety of applications. It can be used in applications that require level translation of data signals between TTL levels and LVCMOS levels. This includes systems with mixed logic levels, mixed speed systems where the devices need to be mixed across various logic families and mixed voltage/temperature systems. It can also be used in applications that require level shifting between different component logic families. In addition, the device can be used for interfacing with external memory or processors, performing data transfer and data conversion between the two systems.Working PrincipleThe SN74LVC245APWRG3 functions as two independent 4-bit buffers, each with separate Output Enable (OE) inputs and Output Enable (OE) outputs. The device transmits data from the A bus to the B bus or from the B bus to the A bus depending on the logic level at the Output Enable (OE) input. The Output Enable (OE) output is activated when the Output Enable (OE) input is high. If the Output Enable (OE) input is low, the outputs are in the high impedance state. The 3-State bus inverter is used to convert the output data bits between differential channel and single-ended logic inputs/outputs.Power SupplyThe SN74LVC245APWRG3 operates on a single power supply with power supply voltage ranging from 1.65V to 3.6V. It has an input voltage range of 1.65V toVCC and an output voltage range of 0.45V toVCC+0.3V. The output voltages is lower than the input voltage, so no level-shifting is used to make the connection between the two.ConclusionThe SN74LVC245APWRG3 provides logic-level conversion between Transistor–Transistor Logic (TTL) logic-level and Low-Voltage CMOS (LVCMOS) logic level. The device is an octal bus transceiver with an integrated 3-State bus invert buffer and is designed to provide automatic interface between data lines of standard TTL levels and CMOS logic with VCC operating from 1.65V down to 1.2V. The device is ideal for a variety of applications including level translation of data signals, mixed logic levels, mixed speed systems and interfacing with external memory and processors. The device can also be used for level shifting between different component logic families. The device is available in a 28-pin SOIC package and is rated for operation over a temperature range of -40°C to +85°C.
