Product details

It operates from 2V to 5.5V, making it suitable for mixed-voltage systems where a 3.3V core interfaces with 5V-tolerant peripherals. The 3-state outputs let you share a data bus with other devices by asserting the output-enable pins. The 20-SOIC wide-body package (7.50mm width) is a common footprint for medium-density logic, and the surface-mount format suits automated assembly lines.

Supply voltage and drive – sizing for the rail

The 2V to 5.5V supply range means this part works in 3.3V and 5V systems without a level translator. At 3.3V, the 16mA output drive is enough to switch a small-signal MOSFET gate or drive a 5V TTL input through a pull-up. The inverting logic is useful for active-low enable signals or complementing a control line.

Lifecycle and compliance – no end-of-life risk

It is ROHS3 compliant, meeting the latest EU restrictions on hazardous substances.
