Frequently Asked Questions
What supply voltage range does the SN74LVCH245ADWG4 support?
The SN74LVCH245ADWG4 operates from a supply voltage of 1.65 V to 3.6 V, making it suitable for 1.8 V, 2.5 V, and 3.3 V logic systems. Its inputs are also tolerant of signals up to 5.5 V, enabling direct interfacing with 5 V TTL logic without additional level-shift components.
How many data channels does this transceiver provide and what is the output drive strength?
The device provides 8 bidirectional data channels with 3-state outputs capable of sourcing or sinking 24 mA. This drive strength supports bus loads of up to 50 pF and allows the transceiver to drive multiple downstream devices on a shared data bus without external buffers.
In which applications is the SN74LVCH245ADWG4 most commonly deployed?
It is most commonly used in memory bus buffering, microprocessor data bus expansion, and voltage-level translation between 3.3 V and 5 V subsystems. Additional applications include FPGA I/O isolation, industrial PLCs, and backplane signal routing where bidirectional 8-bit data paths operating at up to 3.6 V are needed.
Can the SN74LVCH245ADWG4 replace older 74LVCH245 variants, and are there pin-compatible alternatives?
Yes, the SN74LVCH245ADWG4 is pin-compatible with standard 74LVC245 devices in a 20-pin SOIC package and shares the same 1.65 V to 3.6 V operating range. It can also be cross-referenced with the 74AHCT245 for 5 V applications, though the supply voltage range differs and the designer should verify timing and drive specifications before substitution.
