Product details

What this buffer does and where it fits

The Texas Instruments SN74ALS1035DR is a hex (six-element) non-inverting buffer from the 74ALS family, each element handling one bit. The defining feature is the open-collector output.

24 mA sink — what it means for your pull-up and load

Each output can sink up to 24 mA when driven low. That sink current determines the minimum pull-up resistor value and the number of standard TTL loads one output can drive.

Active lifecycle — no LTB risk for BOM planning

ROHS3 compliance is confirmed.

Frequently asked questions

What is an open collector output and why does it matter?

An open-collector output has the transistor's collector left unconnected inside the IC — it can only pull the output pin low (sink current) or release it to high impedance. To get a logic-high level, an external pull-up resistor to the positive supply is required. This allows wired-OR connections (multiple outputs tied together), level translation (pull-up to a different voltage than the chip's VCC), and driving loads like relays or LEDs that need more current than a standard push-pull output can source.
