SN74ALS191AN Description

***roFlash: Counter Single 4-Bit Async Binary UP/Down 16-Pin PDIP Tube

***as Instruments: 4-Bit Synchronous Up/Down Binary Counters 16-PDIP 0 to 70

***fin: Integrated Circuit TTL 74ALS191/SN74ALS191AN TEXAS INSTRUMENT ALS N16

***ark: IC, 4BIT BINARY UP/DOWN COUNTER, DIP-16

***eco: SYNC UP/DOWN BINARY COUNTER <AZ

***ser: Logic - Counters 4bit Synch Up/Dn

***AS: The 'ALS191A are synchronous 4-bit reversible up/down binary counters. Synchronous counting operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincidentally with each other when instructed by the steering logic. This mode of operation eliminates the output counting spikes normally associated with asynchronous (ripple-clock) counters.

***AS INSTRUMENTS INC: The outputs of the four flip-flops are triggered on a low-to-high-level transition of the clock (CLK) input if the count enable () input is low. A high at inhibits counting. The direction of the count is determined by the level of the down/up (D/U\) input. When D/U\ is low, the counter counts up, and when D/U\ is high, the counter counts down.

***AS INSRUMENT: These counters feature a fully independent clock circuit. Changes at the control inputs ( and D/U\) that modify the operating mode have no effect on the contents of the counter until clocking occurs. The function of the counter is dictated solely by the conditions meeting the stable setup and hold times.

***AS INSRUMENT: These counters are fully programmable. Each output can be preset to either level by placing a low on the input and entering the desired data at the data inputs. The output changes to agree with the data inputs independently of the level of the clock input. This feature allows the counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs.

***AS INSTRUMENTS INC: CLK, D/U\, and are buffered to lower the drive requirement, which significantly reduces the loading on (current required by) clock drivers, for long parallel words.

***: Two outputs are available to perform the cascading function: ripple clock and maximum/minimum count. The latter output produces a high-level output pulse with a duration approximately equal to one complete cycle of the clock while the count is minimum (0) counting down or maximum (15) counting up. The ripple-clock output () produces a low-level output pulse under those same conditions, but only while the clock input is low. The counter easily can be cascaded by feeding the ripple-clock output to the enable input of the succeeding counter if parallel clocking is used, or to the clock input if parallel enabling is used. The maximum/minimum count (MAX/MIN) output can be used to accomplish look ahead for high-speed operation.

***ASIN: The SN54ALS191A is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS191A is characterized for operation from 0°C to 70°C.
