The SN74LV163ADBR: Reset is synchronous — the counter clears on the next clock edge, not immediately, which avoids race conditions in state machines that need the reset to align with the clock domain. Housed in a 16-SSOP (0.209-inch body width, 5.30 mm height), surface-mount; the 0.025-inch pitch demands a standard fine-pitch solder profile but no underfill for most reflow processes.
ROHS3 compliant per the lifecycle record.
The SN74LV163ADBR is rated for a maximum count rate of 90 MHz. At that frequency the counter output transitions every 11 ns; the downstream latch or register must have a setup time shorter than that window to avoid metastability.
