onsemi Counters, Dividers 74F162APC

The 74F162APC is a high-speed synchronous BCD decade counter designed for applications requiring programmable dividers. It operates in the BCD (8421) sequence and features synchronous counting and loading capabilities. The device includes a Synchronous Reset input that allows for simultaneous resetting of all outputs on the rising edge of the clock, overriding counting and parallel loading functions. This counter supports a typical count rate of 120 MHz and utilizes D-type edge-triggered flip-flops. It has four control inputs,ÄîSynchronous Reset (SR), Parallel Enable (PE), Count Enable Parallel (CEP), and Count Enable Trickle (CET),Äîwhich determine its operational mode. The counter can be configured for counting, loading, or holding states based on the input signals. The Terminal Count (TC) output indicates when the counter reaches state 9, and it is fully decoded to prevent erroneous outputs. The 74F162APC is available in a 16-Lead Plastic Dual-In-Line Package (PDIP), making it suitable for various electronic applications where space and performance are critical.
