Separate Latch Enable and Output Enable inputs are provided for each register to permit independent control of inputting and outputting in either direction of data flow. The A outputs are guaranteed to sink 24 mA while the B outputs are rated for 64 mA. Features s 8-bit octal transceiver s Back-to-back registers for storage s Separate controls for data flow in each direction s A outputs sink 24 mA s B outputs sink 64 mA Ordering Code: Devices also available in Tape and Reel.

The strobe must be at a low logic level to enable these devices. The 3STATE outputs permit direct connection to a common bus. When the strobe input is HIGH, both outputs are in a highimpedance state in which both the upper and lower transistors of each totem-pole output are OFF, and the output neither drives nor loads the bus significantly. When the strobe is LOW, the outputs are activated and operate as standard TTL totem-pole outputs. To minimize the possibility that two outputs will attempt to take a common bus to opposite logic levels, the output control circuitry is designed so that the averag

Università degli studi della Calabria - Facoltà di Ingegneria – A. A. 2008/2009 Modalità di svolgimento della prova finale di Matematica di Base. Il superamento della Prova di Matematica di Base comporta l’estinzione del debito formativo. Ogni studente è tenuto a presentarsi in aula munito di libretto universitario o di un documento di riconoscimento in corso di validità. È consentito l’utilizzo di appunti e testi durante la prova. Non è consentito l’utilizzo di calcolatrici di alcun tipo. È necessario tenere i cellulari spenti durante la prova. La prova consiste in 15 quesiti a risposta multipla ed ha la durata di un’ora e trenta minuti. Ogni compito è numerato da 1 a 10. Per ogni domanda le possibili risposte, di cui una sola corretta, sono contrassegnate dalle lettere A, B, C e D. Le eventuali risposte ritenute esatte vanno indicate in modo chiaro con una croce. Una risposta vale 3 punti se esatta, -1 punto se errata, 0 punti se non data. Il punteggio della prova è la s
