Decade Up/Down Counter with Clear IC – 74HC192

Description

Decade Up/Down Counter with Clear IC – 74HC192

The 74HC Series 74HC192 IC is an asynchronously presettable BCD Decade and Binary Up/Down synchronous counters, respectively.Presetting the counter to the number on the preset data inputs (P0-P3) is accomplished by a LOW asynchronous parallel load input (PL)\. The counter is incremented on the low-to-high transition of the Clock-Up input (and a high level on the Clock-Down input) and decremented on the low-to-high transition of the Clock-Down input (and a high level on the Clock-up input).

A high level of the MR input overrides any other input to clear the counter to its zero state. The Terminal Count up (carry) goes low half a clock period before the zero counts are reached and returns to a high level at the zero counts. The Terminal Count Down (borrow) in the count down mode likewise goes low half a clock period before the maximum count (9 in the 192) and returns to high at the maximum count. Cascading is effected by connecting the carry and borrow outputs of a less significant counter to the Clock-Up and CLock-Down inputs, respectively, of the next most significant counter.
