Frequently Asked Questions
What is the operating voltage range of the SN74LVC541APW?
The SN74LVC541APW operates from 1.65V to 3.6V, making it compatible with 1.8V, 2.5V, and 3.3V logic systems. This wide range is ideal for low-power portable devices and mixed-voltage board designs.
How does the 3-state output control work on the SN74LVC541APW?
The SN74LVC541APW features two active-low output enable pins (1OE and 2OE). When either enable pin is driven high, the corresponding outputs enter a high-impedance state, effectively disconnecting the driver from the bus. This allows multiple devices to share a single bus without signal contention.
What is the maximum output current of the SN74LVC541APW?
The SN74LVC541APW can sink up to 24mA (IOL) per output, which is sufficient to drive standard CMOS and TTL loads directly. This high drive strength makes it suitable for line driving applications with 50pF load capacitance at high switching speeds.
What package does the SN74LVC541APW come in and what are alternatives?
The SN74LVC541APW is available in a 20-pin TSSOP (TSSOP-20) package, which offers a compact footprint for space-constrained designs. Functional alternatives in other packages include the SN74LVC541ADWR (SOIC-20) and SN74LVC541ADBR (SSOP-20), all offering identical electrical characteristics.
