Fast 16-bit CMOS Bidirectional Transceiver

The LC74FCT164245 and LC74FCT164245T 16-bit 3.3- to-5 V translators are fabricated in an advanced two- metal-layer CMOS technology. These high-speed low- power 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 either 3.3 V system or 5 V system devices. The LC74FCT164245T is optimal for driving large- capacitance loads and low-impedance loads. These output Buffers CAN also be used as an Interface between a dual- power-supply system and external 5 V system equipment. The LC74FCT164245 provides a balanced output drive function that incorporates 25 , (typical value) supply terminating resistors in each output to minimize ground bounce. The LC74FCT164245 features an inter-rail output amplitude and a control-type output edge rate. These features aim at improved signal quality. The LC74FCT164245 is optimal for use in on-board bus Interfaces and in particular, memory data buses. By Sanyo Semiconductor Corporation
