PI74LCX16245 Fast CMOS 3.3V 16-Bit Bi-directional Transceiver Features Description * Functionally compatible with FCT3, LVT, and 74 series 16245 families of products * Tri-State outputs * 5V Tolerant inputs and outputs * 2.0V-3.6V VDD supply operation * Balanced sink and source output drives (24mA) * Low ground bounce outputs * Power down High Impedance inputs and outputs * Supports live insertion * ESD Protection exceeds 2000V, Human Body Model 200V, Machine Model * Packaging (Pb-free & Green available): - 48-pin 240-mil wide plastic TSSOP (A) - 48-pin 300-mil wide plastic SSOP (V) The PI74LCX16245 is a 16-bit bidirectional transceiver designed for asynchronous two-way communication between data buses. The direction control input pin (xDIR) determines the direction of data flow through the bidirectional transceiver. The Direction and Output Enable controls are designed to operate this device as either two independent 8-bit transceivers or one 16-bit transceiver. The output enable (OE) input, when HIGH, disables both A and B ports by placing them in HIGH Z condition. The PI74LCX16245 can be driven from either 3.3V or 5.0V devices allowing this device to be used as a translator in a mixed 3.3/5.0V system.
