简  介:IDT54/74FCT646T/AT/CT FAST CMOS OCTAL TRANSCEIVER/REGISTER (3-STATE) MILITARY AND INDUSTRIAL TEMPERATURE RANGES FAST CMOS OCTAL TRANSCEIVER/ REGISTER (3-STATE) FEATURES: IDT54/74FCT646T/AT/CT DESCRIPTION: Std., A, and C grades Low input and output leakage ≤1A (max.) CMOS power levels True TTL input and output compatibility: – VOH = 3.3V (typ.) – VOL = 0.3V (typ.) High Drive outputs (-15mA IOH, 64mA IOL) Meets or exceeds JEDEC standard 18 specifications Military product compliant to MIL-STD-883, Class B and DESC listed (dual marked) Power off disable outputs permit "live insertion" Available in the following packages: – Industrial: SOIC, SSOP, QSOP, TSSOP – Military: CERDIP, LCC The FCT646T consists of a bus transceiver with 3-state D-type flip-flops and control circuitry arranged for multiplexed transmission of data directly from the data bus or from the internal storage registers. The FCT646T utilizes the enable control (G) and direction (DIR) pins to control the transceiver functions. SAB and SBA control pins are provided to select either real- time or stored data transfer. The circuitry used for select control will eliminate the typical decoding glitch that occurs in a multiplexer during the transition between stored and real-time data. A low input level selects real-time data and a high selects stored data. Data on the A or B data bus, or both, can be stored in the internal D flipflops by low-to-high transitions at the appropriate clock pins (CPAB or CPBA)……
