- | FAST CMOS 16-BIT Registered Transceiver | + | The IDT54/ |
+ | built using advanced dual metal CMOS technology. These high-speed, low-power devices are organized as two independent 8-bit bus transceivers with 3-state D-type registers. | ||
+ | The control circuitry is organized for multiplexed transmission | ||
+ | of data between A bus and B bus either directly or from the | ||
+ | internal storage registers. Each 8-bit transceiver/ | ||
+ | direction control (xDIR), over-riding Output Enable control | ||
+ | (xOE) and Select lines (xSAB and xSBA) to select either | ||
+ | real-time data or stored data. Separate clock inputs are | ||
+ | provided for A and B port registers. Data on the A or B data | ||
+ | bus, or both, can be stored in the internal registers by the | ||
+ | LOW-to-HIGH transitions at the appropriate clock pins. Flowthrough | ||
+ | organization of signal pins simplifies layout. All inputs | ||
+ | are designed with hysteresis for improved noise margin. | ||
