Frequently Asked Questions
What is the operating voltage range of the 74LVC1G240DBVRE4?
The 74LVC1G240DBVRE4 operates across a wide supply voltage range of 1.65V to 5.5V, making it compatible with both 1.8V low-voltage logic systems and traditional 5V TTL/CMOS designs. This flexibility allows it to interface between different voltage domains without additional level-shifting components.
How does the 3-state output of the 74LVC1G240DBVRE4 work?
The 74LVC1G240DBVRE4 features a 3-state output controlled by an active-low output enable (OE) pin. When OE is logic LOW, the output is active and drives the inverted input signal. When OE is logic HIGH, the output enters a high-impedance state, effectively disconnecting the device from the bus and allowing multiple devices to share a common data line.
What applications is the 74LVC1G240DBVRE4 suitable for?
This device is well-suited for bus buffering, signal isolation, GPIO output expansion, and logic level interfacing in embedded systems, IoT devices, industrial controllers, and consumer electronics. Its compact 5-pin SOT-23 package and low power consumption also make it ideal for battery-powered and portable applications.
What is the output drive strength of the 74LVC1G240DBVRE4?
The 74LVC1G240DBVRE4 provides a maximum output current of ±32mA, enabling it to drive multiple standard logic inputs or capacitive loads. This high drive strength is useful in applications where the buffer must fan out to several downstream devices or drive traces with significant parasitic capacitance.
Can the 74LVC1G240DBVRE4 replace 74HC240 or 74HCT240 devices?
The 74LVC1G240DBVRE4 is the single-channel LVC equivalent and can serve as a drop-in replacement for one channel of 74HC240 or 74HCT240 octal buffers in space-constrained designs. It offers improved speed and lower operating voltage compared to HC/HCT logic, but verify pinout and voltage compatibility before substitution in existing designs.
