4-bit synchronous binary counter in the 74ACT family
The CD74ACT161M96 is a 4-bit synchronous binary counter from the 74ACT series, counting up on each positive clock edge with an asynchronous reset. It operates from a 4.5 V to 5.5 V supply.
80 MHz count rate — the speed headroom
The 80 MHz count rate is the maximum clock input frequency. The counter reliably increments on each positive edge across the -55°C to 125°C range.
Asynchronous reset — no clock dependency for clear
The asynchronous reset forces all outputs low the moment the reset pin is asserted, without waiting for a clock edge. This is essential for fail-safe designs where immediate reset is required.
Temperature grade and environment
Rated for -55°C to 125°C operating temperature, this counter operates from a 4.5 V to 5.5 V supply. The 16-SOIC package (3.90 mm width) is a standard surface-mount footprint.
