Product details

74LS hex buffer with open-collector outputs

The SN74LS07DBR is a six-channel (hex) non-inverting buffer from TI's 74LS low-power Schottky logic family. Each of the six buffers drives an open-collector output that can sink up to 40 mA per channel — the rating that matters when you are switching a relay coil, a lamp, or pulling a bus line low through a pull-up resistor.

The 14-SSOP footprint differs from the wider SOIC-14 or the finer-pitch TSSOP-14 — verify the PCB land pattern before committing the BOM line.

It is ROHS3 compliant, so no lead-exemption paperwork for EU-bound assemblies.

Frequently asked questions

What is the SN74LS07DBR used for?

It is a hex non-inverting buffer with open-collector outputs. Typical uses include driving relays, lamps, LEDs, or pulling signal lines low in a wired-OR bus configuration. Each output sinks up to 40 mA, so it handles moderate loads without an external transistor.
