Product details

Each of the two elements can sink 300 mA continuously when the output is low. With open-collector outputs, the load connects between the output pin and a positive supply rail; the driver pulls the output low to energize the load. The 300 mA rating covers most small relays and indicator lamps, but derating is needed if both channels run near the limit simultaneously — the package thermal limit at 70°C ambient will reduce the per-channel capability.

Supply rail and logic interface

The inputs are TTL-compatible, so 3.3 V logic will not reliably drive the inputs to the required high threshold. If your design uses a 3.3 V microcontroller, a level shifter or a different peripheral driver with lower input thresholds is needed.

Package and assembly

The shipping options are Tape & Reel or Cut Tape, which suits both prototyping and volume pick-and-place.

Lifecycle and sourcing

For production BOMs, this part presents no LTB risk.

Frequently asked questions

What is the maximum output current of SN75454BDR?

Each of the two output channels can sink 300 mA when the output is low, as specified in the datasheet. The open-collector outputs require an external pull-up resistor or load connection to a positive rail.

Is SN75454BDR RoHS compliant?

Yes, the SN75454BDR is ROHS3 compliant, meeting the EU RoHS directive without exemptions.
