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. To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pull-up resistor; the minimum value of the resistor is determined by the current sinking ability of the driver. • Compatible with Philips and T.I. AVC Logic family • IOFF supports partial power-down operation • 3.6V I/O Tolerant inputs and outputs • All outputs contain a patented DDC (Dynamic Drive Control) circuit that reduces noise without degrading propagation delay • Industrial operation: –40°C to +85°C • Available Packages: – 48-pin 240-mil wide plastic TSSOP – 48-pin 173-mil wide plastic TVSOP Logic Block Diagram 1DIR 2DIR 1OE 2OE 1A0 2A0 1B0 2B0 1A1 2A1 1B1 2B1 1A2 2A2 1B2 2B2 1A3 2A3 1B3 2B3 1A4 2A4 1B4 2B4 1A5 2A5 1B5 2B5 1A6 2A6 1B6 2B6 1A7 2A7 1B7 2B7 1 PS8524 12/10/01 PI74AVC+16245 2.5V 16-Bit Bidirectional Transceiver with 3-State Outputs 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012 Maximum Ratings (Above which the useful life may be impaired.
