It counts at up to 35 MHz. ## 35 MHz count rate — timing margin in a 5 V bus The 35 MHz maximum count rate sets the upper bound on the input clock frequency the counter can reliably track. The synchronous timing means all bit transitions happen on the same clock edge. ## Asynchronous reset — instant clear without waiting for a clock The asynchronous reset overrides the clock and forces all eight outputs low regardless of the current count state. This is useful for power-on initialization or emergency stop conditions where the counter must zero out immediately, not on the next clock edge. The positive-edge trigger simplifies interfacing with standard 5 V logic families — the count increments on the rising edge, so setup and hold times are referenced to that edge only. ## Commercial temperature range — indoor, controlled environments Rated for 0°C to 70°C, this part is intended for commercial equipment in temperature-controlled indoor settings. ## Lifecycle and supply position The SN74ALS867ADW carries an Active lifecycle status and is ROHS3 compliant. There is no LTB notice or obsolescence risk on this line.","metaTitle":"SN74ALS867ADW 74ALS Binary Counter, 35 MHz, 24-SOIC","metaDescription":"TI SN74ALS867ADW 8-bit synchronous up/down binary counter. 35 MHz count rate, 4.5-5.5 V supply, 24-SOIC.
