LC74FCT164245

Ordering number : EN4628 CMOS LSI LC74FCT164245, 74FCT164245T Fast 16-Bit CMOS Bidirectional Transceiver (Supporting 3.3 to 5 V Operation) Overview The LC74FCT164245 and LC74FCT164245T 16-bit 3.3to-5 V translators are fabricated in an advanced twometal-layer CMOS technology. These high-speed lowpower transceivers are designed to be used as interfaces between 3.3 V and 5 V busses in 3.3/5 V dual power supply systems. The use of these products allows system designers to interface TTL-compatible 3.3 V components to 5 V components. The directionality and output enable control in these products is designed to allow them to be used as either two independent 8-bit transceivers or as a single 16-bit transceiver. In use, the A port is interfaced to the 3.3 V bus and the B port to the 5 V bus. The direction control pin (× DIR) controls the data flow direction and the output enable pin (× OE) disables directionality control and disables both ports. These control signals can be driven from eit...
