The MAX/MIN output produces a high-level output pulse with a duration approximately equal to one complete cycle of the clock while the count is zero (all outputs low) counting down or maximum (15) counting up. The ripple clock output (RCO) produces a low-level output pulse under those same conditions but only while the clock input is low. The counters easily cascade by feeding the RCO to the enable input of the succeeding counter if parallel clocking is used, or to the clock input if parallel enabling is used. Use the MAX/MIN count output to accomplish look-ahead for highspeed operation. DESCRIPTION The device is characterized over full military temperature range The UT54ACS191E is a performance and voltage enhanced version of the UT54ACS191 synchronous 4-bit, reversible updown binary counter. Synchronous counting operation is provided by having all flip-flops clocked simultaneously so that the outputs change coincident with each other when so instructed. Synchronous operation eliminates the output counting spikes associated with asynchronous counters. of -55oC to +125oC. PINOUT 16-Lead Flatpack TopView The outputs of the four flip-flops are triggered on a low-to-highlevel transition of the clock input if the enable input (CTEN) is low. A logic one applied to CTEN 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, it counts down. The counter features a fully independant clock circuit. Changes at control inputs (CTEN and D/U) that will modify the operating mode have no effect on the contents of the counter until clocking occcurs. The counter is fully programmable. The outputs may be preset to either logic level by placing a low on the load input and entering the desired data at the data inputs. The output will change to agree with the data inputs independently of the level of the clock input. The asynchronous load allows counters to be used as modulo-N dividers by simply modifying the count length with the preset inputs. 36-00-04-001 Ver. 1.0.0 B 1 16 VDD QB 2 15 A QA 3 14 CLK CTEN D/U 4 5 13 12 RCO MAX/MIN QC 6 11 LOAD QD VSS 7 8 10 9 C D FUNCTION TABLE 1 FUNCTION LOAD CTEN D/U CLK Count Up H L L - Count Down H L H - Asynchronous Reset L X X X No Change H H X X Aeroflex Microelectronics Solutions - HiRel LOGIC SYMBOL (4) CTEN (5) D/U CLK (14) LOAD (11) A (15) (1) B (10) C (9) D CTRDIV 16 G1 M2 (DWN) 2(CT=0)Z6 3(CT=9)Z6 M3 (UP) (12) 1,2 -/1,3+ G4 C5 (13) RCO 6,1,4 (1) 5D (2) (4) (8) ±7 (3) (2) MAX/MIN QA QB (6) QC (7) QD Note: 1.
