The 1:2 fanout ratio means one input drives two output copies, useful for splitting a clock to two loads without adding a separate distribution IC. ## Supply rail and temperature range The buffer operates from a 3.15V to 3.45V supply — a 3.3V rail with ±5% regulation is fine, but a rail with high ripple or droop under load may push the buffer out of its specified range. ## Active production and sourcing posture Analog Devices lists the LTC6957IDD-4#PBF as Active in production.
