The DS1672U-33+T&R carries an active product status and is ROHS3 compliant.
The T&R suffix indicates Tape & Reel packaging only; the die and electrical specifications are identical. The DS1672U-33 (cut-tape or tube) is the same part in different shipping media. No pinout or functional difference exists.
No. The DS1672U-33+T&R uses an internal oscillator — no external crystal is needed. The binary counter increments from an internal timebase, so the only external components are decoupling capacitors and optionally a backup battery.
