Its defining feature is a synchronous reset — the counter clears on the next rising clock edge, not immediately when the reset line goes low. This matters in designs where the reset timing must align with the clock domain, avoiding the glitch window that an asynchronous reset can introduce. The part counts up only, triggered on the positive edge, with a maximum count rate of 36 MHz. ## Lifecycle and sourcing posture TI lists the SN74HC163PWR as Active and ROHS3 compliant.","metaTitle":"SN74HC163PWR 4-bit synchronous binary counter, 36 MHz","metaDescription":"TI SN74HC163PWR 4-bit synchronous binary counter with synchronous reset. 36 MHz count rate, 2 V to 6 V supply, -40°C to 85°C.

At lower supply voltages (down to 2 V) the achievable frequency will be lower, so leave timing margin if running near the limit."},{"question":"Is SN74HC163PWR synchronous or asynchronous?","answer":"It is a fully synchronous counter — both the count operation and the reset are clocked on the rising edge. This distinguishes it from the 74HC161, which has an asynchronous reset that clears the counter regardless of the clock."},{"question":"Is SN74HC163PWR a direct replacement for SN74HC163AN?","answer":"The SN74HC163PWR is the same 4-bit synchronous binary counter in a surface-mount TSSOP-16 package, while the SN74HC163AN is the through-hole DIP-16 variant.
