Supply voltage and output drive — what they mean for the bus
The 2.7V–3.6V supply range is the first thing to check: this part is strictly a low-voltage device. It will not tolerate a 5V rail, so if your legacy backplane runs at 5V, you need a level translator or a 5V-tolerant family like 74FCT. The output drive is specified at two levels — 12mA/12mA and 24mA/24mA — depending on the supply and load conditions. For a heavily loaded bus with multiple fan-outs, the 24mA option keeps signal edges clean without adding external line drivers. On a lightly loaded point-to-point link, the 12mA setting saves a few milliamps of dynamic current.
Industrial temperature and package fit
The -40°C to 85°C rating covers most factory-floor and outdoor telecom cabinets. It is not an automotive-grade part.
Lifecycle and sourcing posture
The 74ALVC162245PAG8 carries an Active product status and is ROHS3 compliant. There is no NRND flag, no last-time-buy notice, and no official successor — it remains a current-production part suitable for new designs and BOM freeze. No LTB risk to plan for.
