It counts up on each positive edge of the clock, with a synchronous reset that clears the outputs without waiting for the next clock edge — a feature that avoids the glitch risk of asynchronous reset in state-machine designs. The 90 MHz count rate gives enough headroom for most industrial timing and sequencing applications, and the 2 V to 5.5 V supply range lets it bridge 3.3 V and 5 V logic domains directly. Housed in a 16-SOIC package, it is rated for -40°C to 85°C, covering factory-floor and outdoor telecom environments. ## 90 MHz count rate — timing margin in practice At 90 MHz the SN74LV163AD runs nearly 3.3× faster than the CD74HCT390E (27 MHz), which matters when you are counting encoder pulses or dividing a high-speed clock in a PLL feedback path. The synchronous reset means the counter clears on the next clock edge, not immediately — so if you need a glitch-free reset that aligns with the system clock, this part delivers it without external synchronisation logic. The positive-edge trigger matches the majority of FPGA and MCU clock outputs, simplifying the interface. ## Active production — no LTB pressure The SN74LV163AD carries an Active lifecycle status and is ROHS3 compliant. There is no last-time-buy notice or NRND flag, so it is safe to qualify for new production builds. The 74LV series is a mature, widely second-sourced logic family, so supply continuity is solid through both TI and alternate vendors.","metaTitle":"SN74LV163AD 4-Bit Binary Counter, 90 MHz, 16-SOIC","metaDescription":"SN74LV163AD 4-bit synchronous binary counter from TI's 74LV series. 90 MHz count rate, 2 V to 5.5 V supply, -40°C to 85°C.
