State changes of the counter are synchronous with the LOW-to-HIGH transition of the Clock Pulse Input. DILC-16 FPC-16 ORDER CODES PACKAGE FM EM DILC FPC M54HC191D M54HC191K M54HC191D1 M54HC191K1 An asynchronous parallel load input overrides counting and loads the data present on the DATA inputs into the flip-flops, which makes it possible to use the circuits as programmable counters. A count enable input serves as the carry/borrow input in multi-stage counters. Control input, Down/ Up, determines whether a circuit counts up or down. A MAX/MIN output and a Ripple Clock output provide overflow/underflow indication and make possible a variety of methods for generating carry/borrow signals in multi-stage counter applications. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
