Frequently Asked Questions
How many channels does the SN74LV245ADWE4 support and in which direction can they transfer data?
The SN74LV245ADWE4 provides 8 bidirectional channels, with a common DIR pin controlling whether data flows from the A bus to the B bus or vice versa, supporting full 8-bit parallel bus bridging in both directions.
What output current capability does the SN74LV245ADWE4 provide for bus-loading scenarios?
The SN74LV245ADWE4 supports a maximum output sink current of 50 mA (I_ol) and is rated for up to 50 pF load capacitance per output, allowing it to reliably drive heavily loaded data buses found in embedded processor and memory expansion designs.
Which package does the SN74LV245ADWE4 use and is it suitable for automated SMT assembly?
The SN74LV245ADWE4 is housed in a 20-pin R-PDSO-G20 SOIC package with standard 1.27 mm pin pitch, making it fully compatible with automated surface-mount pick-and-place assembly and reflow soldering processes.
When is the SN74LV245ADWE4 a better choice than a unidirectional buffer for a microprocessor data bus?
The SN74LV245ADWE4 is preferred over a unidirectional buffer whenever the microprocessor both reads and writes to external peripherals over a shared 8-bit bus, since its bidirectional architecture and direction pin eliminate the need for two separate unidirectional devices, saving board space and cost.
