WebThe 74HC191 is an asynchronously presettable 4-bit binary up/down counter. It contains four master/slave flip-flops with internal gating and steering logic to provide asynchronous preset and synchronous count-up and count-down operation. Asynchronous parallel load capability permits the counter to be preset to any desired value. WebThe Binary Counter is used to created up counters, down counters, and up/down counters with outputs of up to 256-bits wide. Support is provided for one threshold signal that can be programmed to become active when the counter reaches a user defined count. The upper limit of the count is user programmable and the counter’s increment value … WebCD40192b Presettable BCD Up/Down Counter and the CD40193B Presettable Binary Up/Down Counter each consist of 4 synchronously clocked, gated "D" type flip-flops connected as a counter. The inputs consist of 4 individual jam lines, a PRESET\ ENABLE\ control, individual CLOCK UP and CLOCK DOWN signals and a master RESET. ... brain and spine center newport hospital
