Synchronous 4-Bit Up/Down Counters DM54LS190 DM74LS190 DM54LS191 DM74LS191 Synchronous 4-Bit Up Down Counters with Mode Control
May 1989
DM54LS190 DM74LS190 DM54LS191 DM74LS191 Synchronous 4-Bit Up Down Counters with Mode Control
General Description
These circuits are synchronous reversible up down counters The LS191 is a 4-bit binary counter and the LS190 is a BCD counter Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs change simultaneously when so instructed by the steering logic This mode of ope |

Synchronous 4-Bit Up/Down Counter with Mode Control DM74LS191 Synchronous 4-Bit Up/Down Counter with Mode Control
August 1986 Revised February 1999
DM74LS191 Synchronous 4-Bit Up/Down Counter with Mode Control
General Description
The DM74LS191 circuit is a synchronous, reversible, up/ down counter. Synchronous operation is provided by having all flip-flops clocked simultaneously, so that the outputs change simultaneously when so instructed by the steering logic. This mode of operation eliminates the output counting spikes normally associated with asynchronous (ripple c |

Up/Down Decade Counter with Separate Up/Down Clocks 54LS192 DM74LS192 Up Down Decade Counter with Separate Up Down Clocks
May 1992
54LS192 DM74LS192 Up Down Decade Counter with Separate Up Down Clocks
General Description
The ’LS192 is an up down BCD decade (8421) counter Separate Count Up and Count Down Clocks are used and in either counting mode the circuits operate synchronously The outputs change state synchronous with the LOW-toHIGH transitions on the clock inputs Separate Terminal Count Up and Terminal Count Down outputs are provided which are used as the clocks |

Synchronous 4-Bit Binary Counter with Dual Clock DM74LS193 Synchronous 4-Bit Binary Counter with Dual Clock
September 1986 Revised March 2000
DM74LS193 Synchronous 4-Bit Binary Counter with Dual Clock
General Description
The DM74LS193 circuit is a synchronous up/down 4-bit binary counter. Synchronous operation is provided by having all flip-flops clocked simultaneously, so that the outputs change together when so instructed by the steering logic. This mode of operation eliminates the output counting spikes normally associated with asynchronous (rippleclock) counters |
